SRB400CS-24VDC

  • Two-functions safety monitoring module (double evaluation)
  • Level 1: Reset without edge detection, Optional Automatic reset function, Level 2: / Opener (NC) Opener (NC)
  • 2 x 2 enabling paths with different shut-down behaviour, e.g. emergency exit opens both enabling paths (level 1); guard door monitoring only opens the second enabling path (level 2)
  • Suitable for signal processing of potential-free contacts, e.g. Emergency Stop command devices (level 1), position switches with safety function, solenoid interlocks and safety sensors (level 2)

Notes
Note (General)
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
Note (Short-circuit recognition)
Level 1
Circuit example
Note (Wiring diagram)
The wiring diagram is shown with guard doors closed and in de-energised condition.
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.
The control recognises cross-short, cable break and earth leakages in the monitoring circuit.
Input level: the example shows a 2-channel control of an Emergency Stop command device (level 1) with external reset button (R), and guard door monitoring (level 2) with feedback circuit (H2).
Automatic start (level 1): The automatic start is programmed by connecting the feedback circuit to the terminals X1/+24 V DC. Automatic start (level 2): The automatic start is programmed by connecting the feedback circuit to the terminals X2/+24 V DC. If the feedback circuit is not required, establish a bridge.
