Compactness means that PROTECT SELECT in a 52 mm housing can replace up to 6 safety modules with protection level up to PL, SIL3.
There are 18 digital safety inputs to control all common safety sensors e.g. emergency stop command devices, position switches, solenoid interlocks
with and without interlocking function and magnetic safety switches. There are also 4 safety transistor outputs and 2 safety relay outputs.
There are also 4 optional signal outputs and 2 safety analog inputs that allow control of critical process variables (temperature, pressure, flow, etc.).
