DHC-400 DC Digital High-Resolution Controller

Peaktronics DHC-400 DC Digital High-Resolution Controller

The Peaktronics DHC-400 is a high-performing digital positioner used to control DC actuators. It provides 450 points of resolution, with quarter-turn actuators ranging from 2 sec to 120 sec. 

The DHC-400 has features that will improve any actuator and is still to install. Plus, you can generally use this positioner as a replacement for a standard size DMC-100 controller if you wish to improve actuator performance.
