Description
Model 5C7-252 Series Controllers are temperature controls with an RS-232 communications port allowing them to be confiqured for different modes of operation from a personal computer. The controllers are provided with PC Software and a Graphical user interface. (GUI) Once the controller is configured, the PC may be disconnected and the controller can be operated as a stand-alone unit. Communications can be re-established at any time to adjust 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 operated from either 120 VAC or 240 VAC which is field selectable. Input and power outputs are made via .250 and .110 fast tab connections. The sensor inputs and RS232 connections are via a Eurostyle screw terminal strip. A solid state relay output provides current capability up to 15 amperes at either 120 VAC or 240 VAC. In addition, an alarm output solid state relay is provided which is rated for 0.5 ampere at either 120 VAC or 240 VAC plus a 5 volt drive signal 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 consists of proportional bandwidth (P), integral gain in repeats per minute (I), and the derivative rate in minutes (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 thermistor 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 thermistor selections have an operating temperature range of -20°C to 110°C for TS67, 50°C to 225°C for TS133, and 70°C to 300°C for TX2A.
Software
In addition to the included configuration programe there are FREE ActiveX with Visual Basic examples and LabView drivers available from a third-party source.   Also available here is a Windows application called ThermalManager. This application allows multiple views of attached temperature controllers, allows all parameters to be adjusted and also includes a datalogging function.
