5R7-388 RoHS Thermocouple Controller with RS-232

Model 5R7-388 is a RoHS Compliant bi-directional electronic temperature controller for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications. The “H” bridge configuration of the solid state MOSFET output devices allows for the bi-directional flow of current through the thermoelectric modules. Highly efficient N-channel output devices are used for this control mode.

This controller is PC programmable via an RS232 communication port for direct interface with a compatible PC. The easily accessible communications link permits a variety of operational mode configurations. Field selectable parameters or data acquisition in a half duplex mode can be performed. Once the desired set parameters are established, the PC may be disconnected and Model 5R7-388 becomes a unique, stand alone controller.
