Description
The IMO safety relay SR2C is equipped with force-guided and
redundant relays (two safety relay output contacts) enabling the
SR2C to interrupt quickly and safely the dangerous parts of the
machine.
Additionally each ON/ OFF cycle ensures an automatic functional
monitoring, which ensures that if a safety circuit failure occurs
switching ON is possible (self-monitoring).
Applications include one and two channel emergency stop and
two channel safety gate monitoring. A single-fault occurrence
does not lead to the loss of the safety function. It will be
recognised at or before the next requirement of the safety
function. The SR2C satisfies Stop category 0 according to
EN60204-1 and risk category 4 according to EN954-1.
