HVAC Products

ECP

EC Products was established in 2006, distributing imported products from around the world to the UK HVAC market.

In 2008, the decision was made to invest in developing and manufacturing our own product range, to be produced at our premises in Hounslow.

This introduction enabled ECP to respond to customer demand for next-day delivery, supplying British-manufactured, high-quality products.

They are now the one-stop shop for both BMS peripherals and everything panel builders require, from panel lamps to Steel enclosures.

    Current Monitoring Relay – CMR5-VFC

    £23.50 Exc. VAT Add to basket

    The Current Monitoring Relay is designed to monitor Current to equipment and can be set to switch the voltage-free contact at a set current. There is an adjustable time delay to eliminate current peaks. It can also be used with a current transformer to monitor higher currents. It has an LED indicator and is Din-rail mounting.

  • Relay and IO Modules

    Dual Phase Cut Module 30VA per channel – IOPC2

    £92.00 Exc. VAT Add to basket

    The 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.

  • Relay and IO Modules

    Eight Stage Relay Module – IOR8

    £70.00 Exc. VAT Add to basket

    The IO-RM8 is intended for use with BMS controllers to convert an analogue control output to staged or sequenced relay modes.
    LEDs indicate correct operation, and Hand/Off/Auto jumpers ease commissioning.

  • Relay and IO Modules

    Electro-pneumatic Converter – IOEPC

    £250.00 Exc. VAT Add to basket

    The IOEPC is an electric-to-pneumatic transducer which converts an analogue input signal to a proportional pneumatic output. The unit will automatically modulate its control valve to regulate the branch-line pressure to the selected set point, as determined by the input signal.

    Two Stage Relay Module – IOR2

    Original price was: £39.50.Current price is: £35.00. Exc. VAT Add to basket

    This 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 Exc. VAT Add to basket

    The 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.

  • Air

    Voltage to Current Conversion Module – IO-VI

    £43.00 Exc. VAT Add to basket

    The IO-VI is designed to convert a 0-10Vdc input signal to a 4-20mA current output. The IO-VI is supplied in a DIN Rail carrier suitable for mounting on a TS35 DIN Rail section and features high-quality rising clamp terminals for ease of connection. The unit is powered by 24 Vac/dc and can power a current-loop signal.
