Application
The relays are intended for installations where high operating
requirements exist, on operating time, contact rating (heavy
breaking duty) or else where normal relays of industrial type
are not suitable.
The relays are especially suitable in protection and control
circuits. Models exist that are very suitable for high corrosive
atmosphere or seismic areas. Tripping, interblocking and
multiplying functions are easily achieved with single relays or
combinations of relays.
Special requirements can be met by using different contact
types, twin contacts, bridge contacts or dry-reed contacts.

RXME 1
Types RXMA 1, RXMA 2 and RXMM 1 are used as position
repeat relays, as interposing relays in control equipment and
as output relay in protection relays.
Type RXMM 1 is a space saving relay with two coils, each with
3 contacts for applications where few contacts are needed.
Type RXMS 1 is particularly suitable as tripping relay due to its
extremely short operate time. A special variant, which is not
influenced by capacitive discharges at earth fault and which
also has improved insulation across open contact, is available
for heavy applications where high disturbance immunity is
required.
RXMS 1, in combination with heavy-duty relays, is used in
high speed tripping assemblies as accessories to protection
relays.
Type RXSF 1 is a signal flag relay intended for use as
operation indicator. A zero voltage type is available and can
be used to supervise dc supply voltages.
Types RXME 1 and RXME 18 are used where a low number of
heavy duty contacts are required e.g. as trip relay. RXME 18 is
a RXME 1 with an operating flag indicator.
Type RXMH 2 is used when many heavy duty contacts are
required. It can be provided with an operating flag indicator,
as an option.

Plug-in units with e.g., diodes, resistors and capacitors are

Connection blocks type RTXE for attachment to the pocket
of the rear side of the terminal bases can be ordered from the
same catalogue.
Drop-out time-lag with a diode
To obtain a dropout delay of a dc relay or to protect an
electronic circuit against transients, a diode unit across the
relay coil (R) can be used. Diode unit, type RXTDA 1, or
terminal base mounted type RTXE can be selected.
If the dropout time (t) in the table is too long it can be reduced
with a resistor (r) connected in series with the diode.

(96000038)
Auxiliary relays can be used in a number of ways with different
accessories to obtain a variety of types of operation. A few
typical circuits are shown below.
–
Drop-out delay can be achieved by connecting a parallel
diode across the relay coil as shown. Please observe the
polarities of the dc voltage and the diode.
When S makes the relay picks up instantaneously. When
S breaks the relay drops out with a time lag caused by the
diode.
Inductive transient protection
The diode also provides transient protection of the relay
and also for the parallel connected devices by reducing the
induced overvoltages (many kV’s) caused by the inductance
of the auxiliary relay upon disconnection from the dc supply
when the energizing contact opens.
Transient protection (and shorter drop-out delays) may also
be achieved by using a parallel connected resistor, thermistor
or varistor across the relay instead of the diode. These
components are available for mounting directly in the rear
pocket of the terminal base using type RTXE component
blocks.

RTXV Control unit
High-speed auxiliary relays can at earth-fault in unearthed DC
voltage systems give unwanted operation.
To avoid the risk that the voltage caused by the earthfault causes unwanted operation on auxiliary relays, we
have designed a control unit, type designated RTXV, to be
connected in series with the terminal of the relay coil.
The control unit connects applied voltage to the relay only if
the voltage is larger than 60-80% of the rated voltage of the
unit. The voltage drop in the control unit is about 2 V.
The control unit is mounted in a component box, which in
its turn can be mounted on the rear of the terminal base of
COMBIFLEXrelays.
For more information, see References on page 19.

Pick-up and drop-out time-lag using a capacitor
The operating time can be reduced for auxiliary relays by
connecting a separate resistor – r in the diagram – in series
with the relay coil K.
The connection reduces the L/R ratio, i.e. the time constant
for the drawn relay coil operating current.
The pick-up time and characteristics of the series resistor
for a number of types of relays are listed in the table 1.
The dispersion of the pick-up time is about ±20% at rated
voltages and up to ±50% if considering voltage range
variations.
The drop-out time of the relay will be approximately the same
as for a relay without the series resistor.
When S makes, the relay K picks up instantaneously and
remain a picked up until C is sufficiently charged. The relay
then drops out, since the current through r and K falls below
the relay drop-out value. (S remains closed all the time).

Design
The contact elements are made of silver, however, gold
elements on the contacts can sometimes be necessary, for
example in sulfuric atmospheres or when the voltage in the
contact circuit is lower than 10 V and the current lower than
10 mA.
Each relay has a dust-tight cover, except the RXMS variants
A and E, and is intended to be mounted on a terminal base.
Terminal bases are available in four sizes. The relays are
fixed to the terminal bases with two or four Phillips No. 2
cross-head screws. Each relay cover has a hole covered by a
removable plastic plug with the exception of RXME 18, RXSF
1 and RXMT 1. Through the hole the armature of the relay
can be activated. Relays with indicating flags have a resetting
knob accessed from the outside of the cover.
The relays are marked with the type designation, Ordering
No., rated voltage, and where applicable, the symbol of the
relay is also shown.
All dc supplied relays, with the exception of RXMS 1 and
RXMT 1, can be supplied with full-wave or half-wave rectified
ac.
For supply with full-wave rectified ac, select relays with a
rated voltage equivalent to the supply voltage.
For supply with half-wave rectified ac, a diode in addition to
the series diode is to be connected in parallel across the coil
and the rated voltage of the relay is to be equivalent to half
the supply voltage. If transients are expected in the supply
voltage, these determine the choice of matching diodes.
Smoothing capacitors are unnecessary in both cases.
The auxiliary relays will operate within a range of 80-110%
of the rated voltage. If the rated voltage is given as a voltage
range, e.g. 110-125 V, the relays will operate within a range
of 80-110 % of each rated voltage between 110 and 125 V.
Permissible temperature range is given in the data table.
6 | Auxiliary, signalling and tripping relays - 1MRK 508 015-BEN Revision: D
Relays with twin contacts
Auxiliary relays used in automatic equipment for control and
regulation must have a very high degree of contact reliability
even at lower voltages. Auxiliary relays with twin contacts fulfil
this requirement. A twin contact has two contact elements on
each contact member and each of these makes independent
and simultaneous contact with the corresponding element
on the other contact member. This gives two parallel current
paths and greatly reduces the risk of contact failures. The
contact sets have contact levellers of wear-resistant material
with a low coefficient of expansion. This means that the
correct contact force is always obtained even in contact units
containing numerous contact springs. Type RXMA, RXMM,
RXMS and RXSF contain twin contacts.
(96000039)
The auxiliary relays in the COMBIFLEX system permit
interchanging between various types of relays chiefly because
the coil terminals are always connected to the same terminal
on the plug-in base of the relay. Relays having the same
contact symbol can be interchanged without alteration of the
connection.
Figure 1: Twin contact
RXMA 1
This relay is designed for dc supply. The outstanding
features of this relay are its low power consumption and long
mechanical life.
A few variants of RXMA 1 is ac operated with a valid
frequency between 50-60 Hz and rated voltage of 115 or 230
V. A half-wave rectifier is built in, connected in parallel across
the coil.
RXMA 2
This relay is a variant of RXMA 1, with a larger terminal plug-in
plate, and a greater number of contacts.
The relay occupies two seats.
RXMA 1 and RXMA 2 have one, two or three sets of contact
stacks. The system voltage across one stack of contacts
must not exceed 300 V dc or 250 V ac. The corresponding
voltage between contact stacks must not exceed 600 V dc or
500 V ac.
to reject induced AC voltages. The SCADA interposing
version of RXSF 1 is in addition designed to provide a higher
operating current in order to even further increase security
against maloperation due to induced AC voltage interference.
RXMM 1
The relay is designed for dc supply. Two smaller type relays
are included in RXMM 1. These relays can each have up to
3 contacts (6 contact springs). Relay RXMM 1 with different
rated voltages for the two relays is also available as an option.
RXSF 1
The unit contains one or two smaller relays with three
contacts and red indicating flags. The flags are reset manually
with an external knob or automatically when the dc is
switched off.
The RXSF 1 is also available as loss-of-voltage relay. The
indicating flag is always automatically reset in this variant.
There are DC voltage and DC current operated versions of the
RXSF 1 relay. See the selection tables on p. 16. The current
operated relay may e.g. be used to indicate that breaker trip
coil current has flown, i.e. as a series trip current flag (target).
SCADA Interposing Relay type RXSF 1
Interposing relays for SCADA equipment must not misoperate
due to induced AC overvoltages that may occur as a result
of a relatively long distance between the RTU and the remote
control panel. Such a misoperation may lead to maloperation
of breaker or isolator open / close commands.
Variant E (7 W) is safe for capacitive discharge through the
coil at dc earth faults. It has also a larger contact gap, which
can withstand 2 kV test voltage.
Because of the high power consumption in variants A and E
these variants should not be continuously energized.
The relay has an additional terminal (28) brought out between
the coil and the series resistor. This terminal is intended for
dropout delay by connecting a diode across the coil.
(96000040)
(RXMA_2.eps)
RXMS 1
This relay is designed for dc supply. It has a very short pickup time, down to 4 ms for a make contact (variant A, 7 W).
Variant B is a low power variant (3 W) with 1,5 ms longer
pick-up time.
Figure 2: RXMS 1
Relays with bridge contacts
Auxiliary relays which are to be used as tripping relays or as
operating relays should have a high breaking capacity, good
contact reliability and be free from risk of contact welding.
These qualities are possessed by relays with bridge contacts.
The contacts have two fixed contact members and a moving
bridge-shaped member. This design with two breaking points
in series gives high breaking capacity.
The moving contact member is designed so that a
considerable sliding motion is obtained between the contact
elements during closing; this increases contact reliability and
reduces the risk of welding.
There is a variant of the well proven relay RXSF 1 that may be
used to reduce the risk of such a misoperation. The RXSF 1 is
designed

Figure 3: Bridge contact
(RXME_1.eps)
RXME 1
This relay is designed for dc supply. It has two or four
contacts.
RXMH 2
This relay has eight heavy duty contacts and can be fitted
with an indicating flag which becomes visible when the
armature picks-up and remains visible after drop-out. The flag
is manually reset by means of a resetting knob in the cover.
For checking the operation the relay has a push-button which
is accessible through a hole in the cover. The relay occupies
two seats.
Relays with single contacts (dry-reed relays)
In certain cases auxiliary relays are used in a highly corrosive
atmosphere or under other conditions where special contacts
are required, e.g. for low voltages and currents such as in
automatic control circuits with static components. For such
applications, auxiliary relays with built-in special contacts, e.g.
dry-reed elements should be used. A dry-reed element has
one fixed and one moving contact of magnetic material. If the
coil, which encircles a dry-reed element with a make contact,
is energized, magnetic flux flows through the contact which
then closes. When the coil is de-energized the contact opens.
In dry-reed relays with break contacts the coil also encircles a
permanent magnet of which the flux holds the contact closed.
When the coil is energized the flux of the permanent magnet
is counter-balanced and the contact opens. When the coil
is de-energized the contact is reclosed by the permanent
magnet. This implies that dry-reed relays with break contacts
are dependent on polarity, and the coil must be connected in
accordance with the symbols in the ordering table.
RXME 18
The relay consists of an RXME 1 relay fitted with a red
indicating flag. The flag becomes visible when the armature
picks-up and remains visible after drop-out. The flag is
manually reset by means of a resetting knob in the cover. The
relay has two contacts.

(96000041)
Types RXME 1, RXME 18 and RXMH 2 contain bridge
contacts.
RXMT 1
RXMT 1 has 2 dc-supplied dry-reed relays, each with one
make or break contact (dryreed element). The relay is very fast
and has a pick-up time of < 1,5 ms.
RXMT 1 should not be positioned alongside relays which have
powerful magnets as they may cause RXMT 1 to remain in the
pickedup position.
Tripping assemblies
Single auxiliary or flag relays of any model may be used
in tripping circuits, depending on requirements. Specially
designed combinations of relays mounted on terminal
bases and apparatus bars are available. These tripping
units combine an ultra-high speed relay, type RXMS1 and
a heavy duty relay for carrying and breaking high currents.
Combinations with latching relays or time relays for prolonged
trip pulse and delayed resetting are available.
(SE970873)
(RXMT_1.eps)
Trip and indication module
An auxiliary trip module for tripping from transformer
protection device, e.g. Buchholz, temperature, etc., is
available. It contains up to 10 inputs and the inputs are safe
for capacitive discharge. A timer provides the required pulse
length.
