PEAKTRONICS
The Peaktronics DHC-100 is a high performance
digital positioner intended to control AC actuators, provid-
ing 450 points of resolution, and can be used with actuators
ranging from 2 sec to 90 sec and rated for 25% duty or
more. The DHC-100 has many automatic advanced fea-
tures that will enhance any actuator while making it easy to
install and set up.
The simple three button control is used to configure
all parameters the unit needs for a wide variety of applica-
tions, and allows the open and closed positions to be easily
set for direct or reversing acting without any rewiring. The
unit can be configured for various command types (4-
20mA, 1-5V, 0-5V, 0-10V, or a digital command), and its
default operation upon loss of command.
Various option modules are easily plugged in to
provide other features such as a position feedback signal
(current or voltage), auxiliary switches, fault relay contact,
or digital communications. A wide range of data is acces-
sible through a digital communications module, providing
additional control or information.
The unit is of single solid construction and is easily
mounted with two screws. The DHC-100 is interchange-
able with the AMC and LRC standard size controllers, and
can be used to upgrade performance for those applications.

FEATURES
• Positions to ±0.1° with quarter-turn actuators ranging from 2 sec to 90 sec (with or with-
out a brake).
• Adaptive Control feature continuously adjusts for load and actuator conditions and
eliminates calibration procedures and auto-cal operations.
• Three button control provides easy setup and eliminates the need for instrumentation.
• Polarity Detection feature allows direct or reverse acting operation without re-wiring.
• Electronic Brake feature can eliminate need for a mechanical brake in many applica-
tions, and extends mechanical brake life when used.
• Stall Detection feature protects actuator motor from a stall condition.
• Automatic Duty Cycle Control feature prevents shutdown of a process due to a ther-
mal overload of the actuator motor, and allows actuators rated for 25% duty or more to
be safely used.
• Operating temperature range of 0 to 60°C
