Wireless I/O Module

Wireless I/O Module

The SignalFire Wireless I/O Module acts as a wire replacement that replicates analog and digital signals over a wireless link between a pair of Wireless I/O Modules. The modules are DIN rail mounted and designed to be easy to use.

The Wireless I/O Modules can also be used with a standard SignalFire Gateway.

  • 4 Analog inputs (0-20mA or 0-5V)
  • 4 Analog outputs (0-20mA or 0-5V)
  • 2 Digital inputs
  • 2 Relay outputs (1 DPDT, 1 SPDT)
  • Powerful 300 mW radio with antenna kit
  • Wide range DC power input. 10 to 30VDC
  • DIN Rail Mount with pluggable screw terminal blocks
  • Status LEDs
  • Class 1 Division 2 Certified, Groups C&D, Temperature Code T5.  Certified to CSA C22.2 No. 213, Conforms to ISA 12.12.01
Point to Point I/O Mirroring Configuration:


The analog/digital inputs on one module can be replicated on the other module (and vice versa)-ideal for stand alone valve control or simple retrofit applications.

SignalFire Remote Node Configuration:


Operates as a remote node with a standard SignalFire Gateway.  All IO data is available at the Gateway as Modbus registers. Supports Modbus writes to control the analog and relay outputs.

Operating Temp:  -40ºC to 80ºC

Power:  10-30 VDC (25mA average @12V no relays energized, additional 15mA max for each energized relay, plus any analog output current)

Analog Inputs:  0-10V max, 0-24 mA max

Analog Outputs: 0-20 mA, 0-5 Volts

Digital Inputs:  Dry contact or 30 volts max (push-pull)

Radio Frequency:  902-928 MHz ISM band, FHSS radio, SMA connector

Relay Outputs:  2A, 60W

Signal-Fire

The SignalFire system is a robust, short-range mesh network designed to give asset managers access to valuable process data. Easy to install and sensor agnostic, the wireless telemetry system can interface with many sensor types such as flow, level, pressure, and temperature, in controlling devices such as pumps, valves, heaters, fans, and lighting. Designed for challenging industrial environments, the SignalFire Remote Sensing System has been deployed in oil and gas fields, irrigation systems, water treatment plants, as well as a variety of other remote applications.
