Actor configuration
Dual-channel control with feedback loop
Suitable for contact amplification or contact multiplication by means of relays or con-

tactors with positively opening contacts.
If the feedback is not required it is to be replaced by a bridge.

Attention:

Acc. to EN 60 079-11:2007 the following is to be considered at the instal-
lation: The distance of ≥ 6 mm between the terminals of the intrinsically safe circuits
to other intrinsically safe circuits should be considered. The distance of ≥ 50 mm
between the terminals of the intrinsically safe circuits to other not intrinsically safe
circuits should be considered.
The phasing of the enabling paths (13-14/23-24) may not be different, i.e. only one

phase may be connected to both terminals.

Function description
The SRB 200EXi-1R is a dual-channel safety relay module for the monitoring of emergency stop control devices, guard monitoring and safety
•
magnet switches.
In the case of closed protection circuits S11-S12 and S21-S22 and closed feedback loop X1-X2 the module starts up after activating and releas-
•
ing and close the enabling paths 13-14/23-24.
By actuation of the emergency stop control device or an other protection device the enabling paths 13-14/23-24 will be opened directly.
•
The module can be restarted when both internal relays K1 and K2 have been dropped out.
