(Category 4)
SR3C
The SR3C is similar to the SR2C except that it
provides for 3 x 8amp Safety contacts plus one
2amp auxiliar y contact. It is available for use
with a 24VDC supply only.

Description
The IMO safety relay SR3C is equipped with force-guided and
redundant relays enabling the SR3C 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
no 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 SR3C satisfies Stop category 0 according to
EN60204-1 and risk category 4 according to EN954-1.
