Description

DCL modulating type electric actuator with smart control pack is controlled by a 4-20mA or 2-10V input control signal. Changing the input control signal results in a proportional position change of the actuator out drive. Meantime output a 4-20mA ratio signal to feedback the actual position of actuator out drive as standard. With motor power on but a loss of control signal, actuator can be set to fail closed, fail open or fail in place.

The smart control pack is fully potted to protect the electronics from vibration and moisture. Actuator passed rigorous EMC test, including EFT, ESD and surge tests, and certified by CSA complied to UL and CSA standard.
