I/O Modules

IO Input / Output Modules IO modules offer the capability for rescaling, converting, isolating and overriding signals from BMS controllers.

I/O-ABM Analogue Override Modules’ are Intended for applications which require independent manual override of analogue output channels from a BMS controller, as a fail-safe in the event of controller failure. IO-ARM for signal rescaling, the I/O-ARM can accept either a voltage or current input which can be rescaled to either a voltage or current output.

IO-AUD R/L to Analogue Module for signal rescaling, the I/O-ARM can accept either a voltage or current input which can be rescaled to either a voltage or current output. IO-DIM Digital Input Multiplexers are intended for use with BMS controllers to expand their input capacity by multiplexing four or six digital signals, or 4 or 6 x 24Vac/dc inputs into a single analogue controller unit. IO-IIM Input Isolation Modules are intended for use with BMS controllers wherever the output signal requires isolation from the supply ground. IO-RM Relay Module range are intended for use with BMS controllers to convert an analogue control output to various switching relay modes.

IO-IIM Input Isolation Modules’ are Intended for use with BMS controllers wherever the output signal requires isolation from the supply ground. The IO-IIM accepts either a current loop or voltage input. The module is powered by 24Vac and the output 0V is floating with respect to the input and supply ground.
