6R7-001

The Bi-directional H-bridge configuration of this controller creates a seamless transition between heating and cooling as it commands the thermoelectric modules. The included PC software makes it easy for the user to change control configurations through the available RS232 or RS485 interfaces. Both interfaces are electrically isolated to virtually eliminate interference from noise or errant signals. The controller can be configured to operate as a standalone unit, and the PC software may be used for constant data acquisition. Temperature may also be set through an optional remote potentiometer or using the 6R7-001 as a differential controller.
