Description of the Model 5C7-461 Temperature Controller

Model 5C7-461 is a Proportional or On/Off temperature controller that accepts Type "J", "K", or "S" Thermocouple inputs (or ±100mV. as a sensor input). 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 5C7-461 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.

An RS485 communications link is provided for direct interface to a PC with a RS485 card or via an  "RS485/RS232 converter".  This allows the controller to be configured for different modes of operation from the PC. The RS485 communication interface is used to select or adjust field parameters or data acquisition in half duplex mode. Up to 32 units per interface are addressable over a maximum of 4,000 feet of communications cable.

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.

Once the controller is configured, the PC may be disconnected and the controller can be left to operate as a stand-alone unit. Communications can be re-established at any time for tuning of the settings. All parameter settings are retained in non-volatile memory.

The controller package consists of a printed circuit card mounted to a metal mounting bracket that is DIN compatible and may be mounted either horizontally or vertically. The controller can be connected to operate from either 110 VAC or 220 VAC. Input and power outputs are made via .250 and .110 inch fast tab connections. The sensor inputs and RS485 connections are made via a Eurostyle screw terminal strip. A solid state relay output provides current capability of 15 amperes at either 110 VAC or 220 VAC. In addition, an alarm output solid state relay is provided which is rated for 0.5 ampere at either 110 VAC or 220 VAC plus a 5 volt drive rated at 20 ma. for an optional LED alarm monitor, solid state relay, or reed relay.

The PC 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 the power on or off, canceling an alarm condition by silencing the PC audio alarm, tuning the controller setting parameters and displaying the current sensor selection.

Controller tuning parameters consist of proportional bandwidth (P), integral gain in repeats per minute (I), and the derivative rate (D) for selecting P, PI, PD, or PID operation. An on/off operating mode with an adjustable hysteresis may also be selected. A controller configuration command allows for additional optional settings.

The configuration mode allows the operator to select the applicable type thermocouple or ±100 millivolt input, type of optional auxiliary input, set control limits for the application, give the controller an identifying name, select either heating or cooling mode, plus select and enable a protective password.

The three thermocouple selections have operating temperature ranges of...

Alarm selections consist of no alarm function, a fixed high and/or low temperature alarm or tracking alarms. These alarms can be selected for either latching or non-latching operation. Reset of the alarms is accomplished via the PC communications interface or an optional local switch.

In summary, here are the features:

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:
