PART #22018-DH - High-Resolution Positioner
Page 2
INTRODUCTION:
The Indelac 22018-DH, also known as DHC-400,
is a high performance digital positioner intended
to control DC actuators, providing 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 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 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 additional control or
information.
ADDITIONAL FEATURES:
10 to 30 VDC operating voltage range with motors rated up to 60A locked rotor or 10A running
current.
Solid state motor driver with thermal and overcurrent protection provides reliable service
beyond 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 supply
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
prevents shutdown of a process due to a thermal overload switch.
Operating temperature range of 0 to 60°C
