Peaktronics Positioner

The DHC-100 positioner is a high performance, high resolution digital positioner. A simple three button control is used to configure ALL parameters that the unit needs for a variety of applications, and eliminates the need for special meters and/or tools for calibration. As long as there is supply power, the unit can easily be field calibrated.

This positioner can be calibrated for various command types (such as 4-20mA, 1-5VDC, 0-5VDC, 0-10VDC, or digital) and also the default operation upon loss of command (such as fail open, fail close, or fail as is). The optional transmitter/auxiliary switch module is installed into the positioner card via plug and socket. This allows a user defined feedback signal of current or voltage, and provides 3-SPSt relay contacts for open position, closed position, and a fault condition.

New DHC postioner - Gen II

Please note: The new Gen II DHC positioner can be easily identified with three LED’s located at the bottom of the positioner. The old style does not have any LED’s.
