FCU Relay Box

EXP7010 is a universal input relay module, which can efficiently switch for both AC input as well as DC input voltages.

This module is compatible with large range of BMS and Standalone Thermostats that require compact power box containing relays, transformer, fuse and connectors inside a single PVC/metal box.

This module significantly reduces panel assembly time and allows easier installation in site.

EXP7010, when assembled inside a PVC enclosure along with a 24VAC transformer, can be widely used for 3-Speed Fan Coil Units.

EXP7010 is available in 3 different types as follows:
• EXP7010-3 : FCU Power Box module with 3 relays.
• EXP7010-4 : FCU Power Box module with 4 relays.
• EXP7010-5 : FCU Power Box module with 5 relays.

In a typical FCU application, relays 1,2 and 3 are used for fan speed control. These relays have an interlock arrangement preventing simultaneous switch-on of any teo speeds. Other relays (only for EXP7010-4 and EXP7010-5) can be used for ON/OFF or floating operation of valve actuator.
