The Soteria DIN Switch Monitor Unit is designed to monitor the state of one or more single-pole, volt-free contacts connected on a single pair of cables, and to report the status. It has a selectable status reporting delay making it suitable for monitoring flow switches.
The Soteria DIN Switch Monitor Unit is designed to be mounted on a 35 mm width DIM Rail inside an enclosure. The unit is not designed for outdoor use unless it is mounted in a suitable weatherproof enclosure.
