Seamless Wireless Monitoring for Switch Inputs
Overview:
Accutech SI10 Wireless Switch Input Field Unit
The Accutech™ SI10 wireless switch input field unit monitors contact switches without field wiring. It supports two switch contacts with debounce filtering or as a counter for state changes up to 5 Hz. Optional switch outputs can control external power sources up to 1 A at 30 Vdc. Data is reported wirelessly to a centralized Accutech base radio up to 3000 ft. (1000 m).
