Description of the Model
or On/Off temperature controller that accepts thermistor inputs. Line
input powers the controller, and line voltage output powers your load.
The quiet, zero-crossing, burst fired output can be used with resistive
heaters, proportionally controlled valves, or simple on/off valves,
and coolers. Use the PC interface to set it's operating parameters into
its on-board memory and from then on it will run unplugged from the PC
as a standalone controller, or use the PC interface to programmatically
control the Model 5C7-252 for temperature control, or to use the
as an AC relay to simply turn on and off AC power, or to use it as a
for data acquisition. A full 15 Amperes of output is available at 110

percent of power applied to the load and alarm status. It allows
of the set temperature, turning output power on or off, tuning the
parameter settings, and displaying the current sensor selection.
The tuning of control parameters includes
of the proportional bandwidth, integral gain in repeats per minute, or
the on/off control hysteresis. There is also a controller configuration
command for additional optional settings.
The configuration mode allows the operator to
select the desired temperature sensor, type of inputs for the

and select either a heat or cool mode.
configuration options include the selection of any one of up to two
temperature sensors for operation over temperature ranges of -4°F

thermistor input, two thermistor inputs for differential control, a
thermistor input plus a remote potentiometer input, or two thermistor

Alarm selections consist of no-alarm

of either a high or low temperature alarm point with auto reset,
the PC audio, and/or disabling the output to the load when in an alarm
condition. In the tracking alarm mode, the high side delta and low side
delta may be set, plus the PC audio and the disable output selections.

The power connection of the heater or cooler
relay is also made with the same type of connector as above.
The RS232 would need a cable with 3 bare
one end (Signal Ground, Transmit and Receive - that fit into our
screw type terminal strip) and, if connecting directly to your
the other end of the cable would have whatever connector your computer
requires (usually a 9 pin or 25 pin connector) to
to your serial port".

For Programmatic Control: Requires appropriate capability in
language. The best process control language to use is the one you
are already familiar with. For certain controllers, a DLL or other
is available - inquire. Upon written request the source code for the
standard configuration and monitoring program can be provided. It is
written in C. For multiple controller applications: we will sell 2
