Relay and IO Modules
Four Channel Digital Input Multiplexer – VFC input – IOD4
£40.95 Add to basketThe 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.

Relay and IO Modules
Dual Phase Cut Module 30VA per channel – IOPC2
£92.00 Add to basketThe IOPC2 converts two 0-10V DC input signals to drive two separate 0-20V 50Hz phase-cut outputs, at 30VA per channel, for the control of small valve or damper actuators. The IOPC2 features an optoisolator that is powered from 24V ac (with a common connection to the input signal) and has Rising Clamp Screw Terminals. The output from the IOPC2 can be boosted to 60VA by using two IOPCA1, 1 per channel.
