Product Description
DIC01 and PIC01 are precise
TRMS AC/DC over+under,
over+over or under+under
current and voltage (selectable
by DIP-switch) monitoring
relays. DIC01 can perform also
DC plus/minus measurement
by short circuiting pins Z3 and
Y1. The devices can be connected to the MI or MP and
A82 or E82 current transformers.
Both relays have two individual set levels with their own
Ordering Key
time delay. Only for DIC01
each set level can work with a
single SPDT relay.
Owing to the built-in latch
function, the ON-position of
the relay output can be maintained. Inhibit function can be
used to avoid relay operation
when not desired (maintenance, transitions).
The LED's indicate the state
of the alarm and the output
relays.

Mode of Operation
DIC01 and PIC01 monitor
both AC and DC current and
voltage. DIC01 can also
monitor positive and negative DC voltage connecting
terminals Y1 and Z3.
Example 1
(no contact input - under+over
voltage - 2 x SPDT N.D. relays
2
(1 x SPDT for PIC01) - TRMS)
DIC01: One relay operates
when the voltage drops below
the under voltage set point
for more than the respective
delay time. It releases when
the voltage exceeds the set
level plus the set hysteresis.
The other relay operates
when the voltage exceeds
the over voltage set point for
more than the respective
delay time. It releases when
the voltage drops below the
set level minus hysteresis.
PIC01: The relay operates
when the voltage drops below
the under voltage set level
for more than the respective
set delay time or when it
exceeds the over voltage set
level for more than the relative set delay time. The relay
releases when the voltage
exceeds the under voltage
set level plus hysteresis and
it drops below the over voltage set level minus hysteresis (the hysteresis is the
same for both set levels).
Specifications are subject to change without notice (02.11.01)

Mode of Operation (cont.)
Example 2
(latch enable active - under+under
current - 2 x SPDT relays (1 x
SPDT for PIC01) - TRMS)
Note
Different delay times can be
used for appropriate reaction
according to the set points.
DIC01: Each relay operates
and latches when the current
drops below the respective
set level for more than the respective delay time. Provided
that the current has exceeded
the respective set level plus
hysteresis, each relay releases when the contact input’s
connection is interrupted.
Example 3
(inhibit enable active - over+over
current with MI CT - DPDT
relay (SPDT for PIC01) - TRMS)
PIC01: The relay operates
when the current drops
below the higher set level for
more than the respective
delay time. Provided that the
current has exceeded the
higher set level plus hysteresis the relay releases when
the contact input’s connections is interrupted.
Provided that the contact
input’s connection is interrupted, the relay operates
when the current flowing in
the MI CT exceeds the lower
set level for more than the
respective delay time. It
releases when the current
drops below the lower set
level minus hysteresis or
DPDT relay (1 x SPDT for
PIC01) - TRMS
Provided that the contact
input’s connection is interrupted, the relay operates
when the current flowing in
the A82-10 CT exceeds the
lower set level for more than
its delay time. It releases
when the current drops
below the lower set level
minus hysteresis or when the
contact input’s pins are connected.

(no contact input - under+over
voltage - 2 x SPDT N.D. relays
- plus/minus DC
One relay operates when the
when the contact input’s
pins are connected.
voltage drops below the
under voltage set point for
Example 4
(inhibit enable active - over+over
current with A82-10 CT -
more than the respective
delay time. It releases when
the voltage exceeds the set
level plus the set hysteresis.
The other relay operates
when the voltage exceeds
the over voltage set point for
more than the respective
delay time. It releases when
the voltage drops below the
set level minus hysteresis.
In this case the spare front
label has to be placed on the
device for proper level
adjustment.
Note
When the inhibit contact is
opened, if the input signal is
already in alarm position, the
delay time needs to elapse
before relay(s) activation.
