Safety relay for emergency stop, safety doors, light grid up to SILCL 3, Cat. 4, PL e, 1- or 2-channel operation, cross-circuit detection, can be retriggered, fall back/on delay 0.2 s to 60 s, 2 enabling current paths, US = 24 V DC, pluggable Push-in terminal block 

The figure shows a version with a screw connection 

## Your advantages 

Up to Cat.4/PL e according to ISO 13849-1, SILCL 3 according to IEC 62061 

- Low housing width of just 12.5 mm 

- Single and two-channel control 

- 2 enabling current paths, 1 digital signal output 

- Manually monitored and automatic activation in a single device 

- Time saving push-in connection, tools not required 

- Potentials can be easily looped through – ideal for BUS applications 

- Intuitive use through colour coded actuation lever 

- Can be combined with the MSTB 2,5 range 

- Quick and convenient testing using integrated test option
