Datasheet - SRB 302X3-24V-230V
Guard door monitors and Safety control modules for
Emergency Stop applications / Monitoring of
electromechanical switchgear / SRB 302X3
• Suitable for signal processing of potential-free outputs, e.g. emergency stop
command devices, position switches and solenoid interlocks
• Suitable for signal processing of outputs connected to potentials (AOPDs), e.g.
safety light grids/curtains
• 3 safety contacts, STOP 0
• 2 Signalling outputs

notice
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
notice - Wiring example
2 channel control shown for a guard-door monitor with two contacts, of which at least one contact has positive break, with external reset button (R).
Relay outputs:
Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided
contacts.
(H2) = Feedback circuit
The control recognises cross-short, cable break and earth leakages in the monitoring circuit.
The wiring diagram is shown with guard doors closed and in de-energised condition.
