GENERAL DESCRIPTION
The Model DLC, Dual Loop Controller, is a full featured, DIN rail mounted,
dual input PID controller. The DLC is designed as a modular building block for
multi-zone process control applications. The controller has two independent
“A” & “B” input channels. Each channel’s input can be configured to accept a
wide range of thermocouple, RTD, 0-10 V, 0/4-20 mA, or resistive signals. Each
channel can also be configured to extract the square root of the input in both
process voltage or process current modes for applications such as flow
measurement using a differential flow sensor.
Channel B can be assigned as a Remote Setpoint for Channel A. The two
time-proportioning or DC Analog outputs can be programmed to control two
independent processes. The two alarms per channel can be configured for
various alarm modes, or provide a secondary control output for heat/cool
applications.
The control and alarm outputs are N channel open drain MOSFETs capable
of switching up to 1 Amp DC. For applications requiring larger loads or A/C
loads, several DIN rail mount relays are available.
The controller operates in the PID Control Mode for both heating and
cooling, with on-demand auto-tune, that establishes the tuning constants. The
PID tuning constants may be fine-tuned through the serial interface. The
controller employs a unique overshoot suppression feature, which allows the
quickest response without excessive overshoot. The controller can be transferred
to operate in the Manual Mode, providing the operator with direct control of the
output, or the On/Off Control Mode with adjustable hysteresis.
The controller’s high density packaging and DIN rail mounting saves time
and panel space. The controller snaps easily onto standard top hat (T) profile
DIN rails.
SAFETY SUMMARY
All safety related regulations, local codes and instructions that appear in the
manual or on equipment must be observed to ensure personal safety and to
prevent damage to either the instrument or equipment connected to it. If
equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not use the controller to directly command motors, valves, or other
actuators not equipped with safeguards. To do so can be potentially harmful to
persons or equipment in the event of a fault to the controller. An independent
and redundant temperature limit indicator with alarm outputs is strongly
recommended.
ALARMS
The DLC’s two solid-state alarms can be configured independently for
absolute high or low acting with balanced or unbalanced hysteresis. They can
also be configured for deviation and band alarm. In these modes, the alarm
trigger values track the setpoint value. Adjustable alarm trip delays can be used
for delaying output response. The alarms can be programmed for Automatic or
Latching operation. Latched alarms must be reset with a serial command. A
standby feature suppresses the alarm during power-up until the temperature
stabilizes outside the alarm region. The outputs can also be manually controlled
with Modbus register or coil commands.
SETPOINT CONTROLLER OPTION
The Setpoint Controller option is suitable for time vs. temperature/process
control applications. The controller allows a profile of up to 20 ramp/soak
segments. Profile conformity is assured by using the Error Band Mode and
Error Band parameter. The Profile Cycle Count allows the profile to run
continuously or a fixed number of cycles. Power-on options automatically stop,
abort, start, resume, or pause a running profile.
