Modbus RS485 digital IO modules are a simple way to add contact sensor monitoring to a RS485 bus. A Modbus contact sensor input module measures industry standard contact sensors. Sensor types include thermostat, temperature, pressure, position, entry, flow, level, etc. Serial based devices that can work with LabVIEW, Python, and other applications that have Modbus communication drivers available. When you have nearby contact sensor signal measurements that you need to make, and have a RS485 port, but do not have a way to read contact sensors.
The DIN-171 digital input module contains six discrete digital inputs for sensing contact closures or switches.
