1.4 EBC30 control components
The EBC30 control is built up around a main board that controls all basic functions. In addition, a Triac board and a relay
board, are available for special functions. The main board controls draft/exhaust and air supply/ intake functions. It can
provide 0-10 V DC signals for Variable Frequency Drives (VFDs), an actuator or other devices accepting a 0-10 V DC control
signal. It also allows interlock of up to 6 appliances for control circuit voltages between 12 V AC and 240 V AC/12 V DC and
240 V DC, and has an integrated Proven Draft Switch (PDS) function. An external PDS is therefore not required.

Main Board
Fig. 1
Two add-on boards are available. A Triac board is available so the control can operate a 1 x 120 V fan or ventilator without
the need for an external drive. A Relay Board is available for applications with more than 6 appliances. The control can only
accept a single add-on board at a time. If there is a need for using the Triac board as well as the Relay board, install the Triac
in the EBC30 and use an ES12, Relay Box in lieu of the Relay Board.
