Module address, bit rate and parity are set with two rotary switches on the front or by software. It is suitable for detecting potential-free switch states, for example electrical limit switches on vent valves or auxiliary Suitable for decentralized mounting on DIN TH35 rail contacts of power contactors. The inputs can be used as according to IEC 60715 in electrical distribution cabinets. contact or voltage inputs.
