The Triac TDC-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 TDC-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, 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.
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 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 60C
