Precision temperature controller
Jun 01, 2013
Precision temperature controllerModel 5R7-388 RoHS-compliant controller is a bi-directional control for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for both cooling and heating applications. The “H” bridge configuration 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 communications link permits a variety of operational mode configurations. Field selectable parameters or data acquisition in a half-duplex mode can be performed. This controller will accept a communications cable length in accordance with RS232 interface speciations. Once the desired set parameters are established, the PC may be disconnected and Model 5R7-388 becomes a stand-alone controller. All parameter settings are retained in non-volatile memory.
