RD-24 General Description 

The RD-24 is a remote input/output device that allows flexibility for applications needing more relays, analog outputs, or analog 
inputs.  Using Modbus communication, you can control multiple I/O based on the application.  The RD-24 requires 24VDC to 
operate and can be used to engage or disengage other equipment such as: fans, louvers, horns, strobes, gas valves, etc.  The 
remote device can be wired in daisy-chain on the gas detector loop to save wire and allows for great flexibility for mounting 
location.
