SRB202CS-24VDC

Descriere

Two-functions safety monitoring module (double evaluation)
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)
2 Signalling outputs
Level 1: Reset without edge detection, Optional Automatic reset function, Level 2: / Opener (NC) Opener (NC)

Note (Contact resistance)	in new state
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
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.; 1 NC contact each time communicates the status of level 1 and level 2
