CPI Project - Louver/Damper Drive Actuator

---

Project Description:

CPI designs and manufactures damper drive assemblies used in industrial applications where precision pneumatic actuation is needed. This particular damper drive unit was customized for to accept a 4-20 mA control signal and hold a proportional angular position from 0 to 90 degrees on an output shaft. On-board heating system allows for cold-temperature environment operation. Position-feedback is provided via a separate 4-20 mA return signal along with tunable limit switches to indicate full open and full closed positions. Output angle is held with a PID controller which allows for precise position holding even under varying loads. Fail systems include the monitoring of supply pressure and control signal - loss of any or both would result in the actuator being forced to the open position. For other dampers, fail-close and fail-freeze could both be accommodated.
