Oven Industries Debuts Bi-directional Electronic Temperature Controller

Oven Industries 5R7-388 RoHS bi-directional electronic temperature controller

Oven Industries announced the 5R7-388 RoHS compliant controller. Model 5R7-388 is a 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. The 5R7-388 is priced at $369.

The 5R7-388 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. This controller will accept a communications cable length in accordance with RS232 interface specification. Once the desired set parameters are established, the PC may be disconnected and Model 5R7-388 becomes a unique, stand alone controller. All parameter settings are retained in non-volatile memory.
