Dual Phase Cut Module 30VA per channel – IOPC2
£76.00 Add to cartThe 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.
