Specifications for 8710 pH / ORP Transmitter -

This has been replaced by 8750 - take me there

This is a two wire device that transmits an analog signal of 4 - 20 mA from input from a pH or ORP sensor. 

The unit uses a Loop Power of 10 to 30 VDC.  This will provide signal for a Signet or other processor controller.
