Overview
TRIATEK's DPT-420/820 Series Damper Blade Position Input to Analog Output Transmitter is a rugged unit which outputs a 4-20mADC or 0-5K W signal proportional to damper blade position. The unit mounts directly to a damper blade via a heavy duty linkage assembly. As the damper blade moves the unit outputs a 4 mADC (optional 5KW ) signal at minimum position and 20mADC (optional 5KW ) signal at maximum position. Zero and span potentiometers on the transmitter version provide the capability to set the minimum and maximum positions at 4 and 20 mADC, respectfully. Each unit is loop powered to eliminate the need to pull separate power wires.

TRIATEK'S Damper Blade Position input to Analog Output Transmitter is designed for commercial or industrial applications requiring closed loop control of dampers.

Common applications would be for HVAC control, building automation, factory automation or energy management systems.

The DPT-420 is housed in a single gang utility box and the DPT- 820 in a gasketed Nema enclosure.
