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.

Six Stage Relay Module – IOR6
£49.00 Add to cartThis IO module is used with DDCs to convert an analogue control output to a staged, reverse-staged or sequenced relay output.
LEDs indicate correct operation and low current draw from a 0-10Vdc controller, which means that the IOR6 can work successfully with most BEM controllers. -

Relay 24Vac Coil
Two Stage Relay Module – IOR2
Original price was: £39.50.£35.00Current price is: £35.00. Add to cartThis IO module is used with DDCs to convert an analogue control output signal to a time-proportional raise/lower, high/low or binary relay output.
Typically, it is used to control valve and damper actuators from an analogue signal. -
FCU Controllers
Volt Free To Voltage Converter – IOFS24-10
£35.00 Add to cartThe IOFS24-10 has been designed to provide 3 DC voltages from voltage-free inputs. The inputs can be adjusted to 0-10 volts. This module can be used for switched fan speed control where a 0-10 volt signal is needed, but only 3 speeds are needed.
