RXPSU6n... with 6 free contacts, only one system
has contacts; in type PSU14n.. with 14 free
contacts, both systems have contacts. In each case
two contacts are required for changing over the
connection of the coils.

High degree of reliability, even when it has been
idle for a long time
RXPSU14n is with mechanical flag type
indicator
6 / 14 contacts with double interruption
Contact configuration can be changed with
ease
Wide range of voltage and contact configuration
The contacts are arranged symmetrically on both
sides of the relay coil and armature assembly in two
stacks. They are easily accessible and the
conversion from N/C to N/O contacts and vice versa
is simple. The maximum rated voltage is 250V d.c. or
a.c. and the material used is hard silver.
The following definitions apply for reset and operate
condition; reset condition - Armature assembly
position is away from the base i.e. the upper system
has been pulsed and lower system is ready to be
pulsed. The flag strips are invisible i.e. white during
this condition.
Operate condition - Armature
assembly position is closer to the base i.e. the lower
system has been pulsed and upper system is ready
to be pulsed. The flag strips are visible i.e. red during
this condition.
Application
For remote and automatic control there is often a
need for contactors which have two stable contact
positions, even in the dead state. This requirement
is fulfilled by changeover contactors type RXPSU...n.
The application of alternate control pulses to the coils
cause the contacts to change from the one state to
the other. If the supply is interrupted, the contacts
remain in their previous position, even when the
voltage is restored.
A transparent, incombustible cover with a gasket
protects the contacts against dirt. The terminals of
the contact stacks themselves permit two wires of
1.5mm diameter maximum to be secured.
Changeover relays must always be mounted with the
contact post horizontal, that is with the base on a
vertical surface. The plug-in relay module occupies
two seats (2u 12C).
Design and principle
The bistable relays in the COMBIFLEX system, type
RXPSU6n and RXPSU14n are composed of the
same constructional elements as the established
contactors type P8n. Two magnet systems are interconnected by a pivoted element. In the type
