The IOD24 module was created and designed to provide a cost-effective and efficient way of handling a large amount of digital input into a Building Management System (BMS).
24 Digital Inputs are multiplexed to provide a single analogue output (0-10V or 4-20mA) which is compatible with most open standard BMS controllers on the market currently.
A Four Channel Digital Multiplexer is £23 each, you get 24 channels for £95, which works out to be £15.83 per 4 channels and also saves panel space and controller IO proxy points.
A Six Channel Digital Multiplexer is £65 each, you get 24 channels for £95, which works out to be £23.75 per 6 channels and also saves panel space and controller IO proxy points.
We would recommend using the 24 digital Input Multiplexer or any Multiplexer for runs, faults, flows, but NOT to use for any life safety items due to a few seconds delay.
