Window Actuator positioning module

The motor drive relay board is mounted in a DIN rail carrier and is designed to provide an interface between the control signals from the BMS to the motors driving the natural ventilation actuators on louvers, windows and blinds to the desired position. It provides three separate bi-directional output drives which can be independently controlled from three 0-10V input signals. The unit is microprocessor controlled and is fitted with 6 x 5A relays arranged in pairs to provide the three output drives. Each drive is independently fused at 5A with a self-resetting fuse and all the drive outputs are supplied from two terminals to which an independent 24V DC supply should be connected. Each output is fitted with a varistor to limit switching transients and has red and green LED’s to indicate relay status (off, opening or closing).

The supply to the unit logic is independent of the above and is 24V AC/DC, the three 0-10V inputs are referenced to this supply.
