24 Channel Digital Input Multiplexer – VFC input
Original price was: £210.00.£95.00Current price is: £95.00. Add to cartThe IOD24 module was designed to provide a cost-effective, efficient way to handle a large volume of digital input to 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.

Relay and IO Modules
Four Channel Digital Input Multiplexer – VFC input – IOD4
£39.00 Add to cartThe Digital Input Expander (4 DIX) allows 4 volt-free inputs to be monitored by a single analogue input channel. The resultant analogue value can be decoded by the A-to-D function module in a BMS controller to produce internal digital status bits for alarm monitoring or other status-input applications.
