Description:
This module is used for converting and multiplying analog signals.Application
The relay unit is primarily designed to activate the triggering control elements of protection systems.
It is mounted in a standard with drawable compartment acc. toDIN, using 3 units and including a female connector, type F
The module contains prototype-tested relays *) with positively driven contacts. The contacts of relays Ki. K2, k3 aregrouped in two circuits and are wired in 2-out-of-3 ordeaccording to the open-circuit principle (external jumpers B18- B20).
Auxiliary contacts can be used to interrogate the individual relay positions.
The module contains six relays, three of which can be wired according to user-specific needs. The contacts of the otherrelays are wired in a 2-out-of-3 pattern.
Relays K4, k5, and K6 are freely available. k4 may be used for instance for the emergency trip push button of a certain protection circuit either based on the closed-circuit or the open-circuit principle. In that case, the required jumpers need to be positioned on the edge connector.
A green light-emitting diode on the front panel indicates when the module is ready for operation.
