Bistable relay types RXPSU6n, RXPSU14n

has contacts; in type RXPSU14n with 14 free contacts, both systems have contacts. In each case two contacts are required for changing over the connection of the coils. 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 DC or AC 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. A transparent, incombustible cover with a gasket protects the contacts against dirt. The terminals of the contact stacks themselves to 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).

Features
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

Application
For remote and automatic controls 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.

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 RXPSU6n with 6 free contacts, only one system
