6. Device overview

6.1 Versions
6.1.1 Device variant ISK 77
The stationary coil core is connected to the safety relay via a cable. The safety relay can be screwed flat to a
base with 4 screws or snapped onto a 35 mm mounting rail. In the case of rail mounting, it is also possible
to cut off the bolt-on feet.
6.1.2 Device variant SPK 77
The stationary coil core is integrated in the safety relay. This device variant is installed directly on the trans-
mission cable via a bracket.

While in the idle state, the resistance between the two connections is approximately 8.2 kΩ. If actuation of
the safety edges is reported, the resistance is less than 100 Ω. In the event of a fault or interruption of safety
edges, the resistance is greater than 100 kΩ
