The Bi-directional or unidirectional H-bridge configuration of the 5R7-002 temperature controller creates a seamless transition between heating and cooling as it commands the thermoelectric modules. The included user friendly PC software makes it easy to change configurations through the RS485 interface which has 1500VAC isolation from the electronic circuitry, virtually eliminating interference from noise or errant signals. Once the 5R7-002 temperature controller is set-up, the computer may be disconnected and the 5R7-002 temperature controller becomes a stand alone unit or the computer can remain connected for data acquisition. The temperature may also be set through the optional display for the 5R7-002 or remote potentiometer. The load circuit is pulse width modulated at 2.7 Khz and delivers a load current of .1 to 25 Amps.
