Peaktronics DHC-400 Manual

PEAKTRONICS
The Peaktronics DHC-400 is a high performance
digital positioner intended to control DC actuators, provid-
ing 450 points of resolution with quarter turn actuators
ranging from 2 sec to 120 sec. The DHC-400 has many
automatic advanced features that will enhance any actuator
while making it easy to install and set up. The DHC-400
can replace a DMC-100 standard size controller in most
applications to upgrade performance.
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. The mul-
ticolor LED Fault indication displays up to 15 different
conditions (including "Low Battery Voltage").
Various option modules are easily plugged into the
unit, providing other features such as a position feedback
signal, auxiliary switches, fault relay contact, or digital
communications. A wide range of data is accessible
through a digital communications module, providing addi-
tional control or information.
•
10 to 30 VDC operating voltage range with motors rated up to 60A locked rotor or 10A run-
ning current.
•
Solid state motor driver with thermal and overcurrent protection provides reliable service be-
yond the life of the actuator motor.
•
Positions to ±0.1° with quarter-turn actuators ranging from 2 sec to 120 sec (with or without a
mechanical brake). Electronic Brake feature can eliminate mechanical brake.
•
Adaptive Control feature continuously adjusts for load and actuator conditions and eliminates
calibration procedures and auto-cal operations.
•
Polarity Detection feature allows direct or reverse acting operation without re-wiring.
•
Stall Detection feature protects actuator motor from a stall condition.
•
Adjustable Motor Current Trip (0-12A) setting limits actuator torque and battery/power sup-
ply current requirements.
•
Electronic Surge Limiting reduces wire size and battery/power supply requirements to 20%
of locked rotor current.
•
Automatic Duty Cycle Control feature prevents motor damage due to overheating and pre-
vents shutdown of a process due to a thermal overload switch.
•
Operating temperature range of 0 to 60°C
