DHC-100 Introduction
The second generation DHC-100 is a high performance digital positioner intended
to control AC actuators, 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 applications, 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. The multicolor
LED Fault indication displays different fault conditions.
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 interchangeable 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.
 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 applications, 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 thermal 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 F.
