The 5R1-001 is a universal AC input temperature controller for resistive heaters. The unit is designed with 1500VAC isolation from the electronic circuitry, which virtually eliminates interference from noise or errant signals. The software is PC programmable and requires no programming experience. The included user friendly PC software makes it easy to change control configurations through the RS232 interface. The RS232 interface has 1500VAC isolation from the electronic circuitry virtually eliminating interference from noise or errant signals. Once the controller is set-up, the computer may be disconnected and the 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 or remote potentiometer. The load circuit delivers a maximum load current of 15 Amps.
