• Automatic/manual-monitored reset
The SRL-1 Safety relay has dual channel, low voltage inputs, two normally open control contact outputs and one normally closed indication contact.
With LED indication to speed up fault finding and a slim 22.5mm DIN rail mounting enclosure the SRL-1 takes up minimum control panel space.
Designed for operation with the Mechan range of non-contact safety switches, the SRL-1 is also suitable for use with dual channel Emergency Stop buttons, or safety devices with 2 safety outputs e.g mechanical safety switches (locking or non-locking).
Depending on installation the SRL-1 can be used in CAT-4 / SIL 3 safety circuits.
