A microprocessor-based actuator with conditioned feedback, the Triatek ACT-FA-8001 Actuator operates on a 24 VAC nominal power supply. Designed primarily for fume hood applications, these units deliver a minimum of 50 in. lb. or 5.6 Nm. torque at rated voltage.
The zero and span and auto-stroking features allow for the sequencing of several motors from the same input signal since the actuator field can be limited between 45 and 90 degrees while the input signal can be set to a portion of 2-10 VDC.
Once programmed, the unit’s settings are permanently stored in the actuator’s non-volatile memory. In the event of a power outage, the unit returns under full torque to its selected fail-safe position.
