Four Channel Digital Input Multiplexer – VFC input – IOD4
£40.95
The 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.
