Oven Industries has released a precision temperature controller with user-friendly software and data retrieval capabilities. The Model 5R7-388 RoHS Compliant controller is a bi-directional control for independent thermoelectric modules or in conjunction with auxiliary or supplemental resistive heaters for 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 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 also be performed. The controller will accept communications cable length in accordance with RS232 interface specifications. 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.
