Relay: Proportional to Tri-State/Floating, 0-10VDC Input

This triac relay module is designed primarily for controlling tri-state actuators in retrofit applications. The REE-5525 allows a low-voltage, low-power, proportional (0-10 VDC) output from a controller or Building Automation System to operate a 24 VAC tri-state (floating) actuator at up to 12 VA and 30 VAC. Optically isolated, zero-crossing triacs control the two (CW and CCW) outputs. If there is a loss of power, no signal will be generated, and the actuator will remain in its last position.

The stage sequence operates in this manner:

• Stage 1 turns on at or below 1.5 VDC and off at or above 3.5 VDC. (It is on at 0 VDC.)
• Stage 2 turns on at or above 9.5 VDC and turns off at or below 7.5 VDC. (It is on at 10 VDC.)
• Both outputs are off between 3.5 and 7.5 VDC.
