Description of the Model 5C7-252 Temperature Controller

Model 5C7-252 is a Proportional or On/Off temperature controller that accepts thermistor inputs. Line voltage 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, heaters, 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 controller as an AC relay to simply turn on and off AC power, or to use it as a DAQ for data acquisition. A full 15 Amperes of output is available at 110 or 220 VAC.

The Model 5C7-252 temperature controller uses an  "RS232 communications interface", allowing it to be configured for different modes of operation using your personal computer. Once the controller is configured, the PC may then be disconnected, leaving the controller as a stand-alone unit.

The personal computer permits the monitoring of actual temperature, set temperature, percent of power applied to the load and alarm status. It allows selection of the set temperature, turning output power on or off, tuning the controller parameter settings, and displaying the current sensor selection.

The tuning of control parameters includes selection 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 application, select a variety of alarm functions, set controlled temperature limits, and select either a heat or cool mode.

Additional configuration options include the selection of any one of up to two different temperature sensors for operation over temperature ranges of -4°F to +212°F (-20°C to +100°C), or +122°F to +437°F (50°C to +225°C). The choice of inputs may be for a single control thermistor input, two thermistor inputs for differential control, a control thermistor input plus a remote potentiometer input, or two thermistor inputs, one being for control while the other is used as a monitor.

Simplified illustrations of the 4 configurations.

Alarm selections consist of no-alarm functions, a fixed type for a high or low condition, or a tracking type which moves with the set temperature at a selectable offset. It also allows the setting of either a high or low temperature alarm point with auto reset, enabling 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.

Implementation Notes

The buyer should be able to rig up the appropriate connections:

• This unit requires an AC cable that connects to the controller using two 0.25 inch quick connects (fast tab connections).
• The power connection of the heater or cooler to the relay is also made with the same type of connector as above.
• The RS232 would need a cable with 3 bare wires on one end (Signal Ground, Transmit and Receive - that fit into our Eurostyle screw type terminal strip) and, if connecting directly to your computer, the other end of the cable would have whatever connector your computer requires (usually a 9 pin or 25 pin connector) to  "connect to your serial port".

Software

A console program for configuring and monitoring the controller comes with the unit, but you can go beyond the program provided and control the temperature controller by means of your own software:

• For Programmatic Control: Requires appropriate capability in a programming language. The best process control  language to use is the one you are already familiar with. For certain controllers, a DLL or other library is available - inquire. Upon written request the source code for the acccompanying, standard configuration and monitoring program can be provided. It is usually written in C. For multiple controller applications: we will sell 2 controllers initially so that you can test your concepts, and then the bulk upon approval.
• For Data Logging: Inquire.
