Use Instructions and Limitations
2.1
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.
