Peaktronics DHC-100 Manual

U.S. Patent 7,466,100 applies to this product
PEAKTRONIC
S
The Peaktronics 2nd generation DHC-100 is a high
performance digital positioner intended to control AC actu-
ators, providing 450 points of resolution with quarter turn
actuators ranging from 2 sec to 120 sec and rated for 25%
duty or more. The DHC-100 has many automatic advanced
features 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, 2-10V, or a Digital command)
and its default operation upon loss of command.
Various option modules are easily plugged into the
unit, providing 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
accessible 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 interchangea-
ble 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 120 sec (with or
without 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
