The unit includes two relays to control actuators, valves and pumps plus two digital inputs for pulse counting or on/off type sensors, such as pressure switches, valve position sensors, etc. For added versatility it also includes an analog input to measure the signal from a 1-5 VDC transmitter. The small DIN rail form factor with low power consumption makes for ease of installation and retrofit in existing electrical cabinets. Appropriate for smaller scale operations, the module has two modes of operation: Point-to-Point or Remote. These modes provide for either a cable replacement for digital and relay signals or for monitoring of sensors and control of actuators. The Point-to-Point I/O Mirroring Configuration allows digital inputs from one module to be replicated on the other module (and vice versa). In standard configuration it operates as a remote node with the company’s standard gateway. All I/O data is available at the gateway as Modbus registers. The unit supports Modbus writes to control the relay outputs. SignalFire node in a SignalFire network, providing longer-range as well as more sophisticated monitoring and control.
Mini Wireless I/O Module for Remote Monitoring and On/Off Automation
The Mini Wireless I/O Module from SignalFire Wireless Telemetry integrates an antenna capable of a 3-mile range, which allows a pair of modules to communicate in a point-to-point mode or directly to a Gateway.
