The following basic units are available for the 3SK1 safety relays:

Standard basic units for simple solutions

The Standard basic units are distinguished by easy handling and they are available with relay and solid-state outputs. They are simply connected to the sensors and actuators, after which the individual devices are wired. This is done particularly fast and easily thanks to cover labeling and the optimized work angle. The basic unit can be easily parameterized for the individual sensors via the DIP switches.

Advanced basic units for flexible solutions

The Advanced basic units offer all product features of the Standard basic units. In addition, they feature increased functionality and flexibility. Additional sensors can be connected via flexibly combinable input expansions. The Advanced device range offers extraordinary ease of handling as the devices need not be wired among each other. The unique device connector is simply plugged on – and operation can be started. This ensures rapid and comfortable commissioning without wiring faults.

The Advanced basic units are available with time delay. The time delay setting is comfortably adjusted via the rotary encoding switch.
