PRODUCT INSTRUCTION SHEET FIG. 3 SECTION 6.0 ELECTRICAL INSTALLATION Power Supply sensor red wire 6.0 ELECTRICAL INSTALLATION. The sensor produces an ap- sensor proximate output of 4 mA in air and 20mA at the top range of black wire free chlorine output (0-2ppm, 0-5ppm, 0-10ppm). NOTE: The supply voltage to the Sensor must be 12-24 V DC with minimum of 250 mA. Maximum load is 1 Watt. The sensor has 3 wires, red (+) , black (-) and clear (shield). Twist together or solder black PLC
