S7-1200 Potentiometer module
The S7-1200 Potentiometer module is an accessory for S7-1200 CPU. Each potentiometer
creates an output voltage proportional to the position of the potentiometer to drive each of
the two CPU analog inputs 0 VDC to 10 VDC. To install the potentiometer:
1. Insert the circuit board ‘fingers’ into any S7-1200 CPU analog input terminal block, and
connect an external DC power supply to the 2-position connector on the potentiometer
module.
2. Use a small screwdriver to make the adjustments: turn the potentiometer clockwise (to
the right) to increase the voltage output, and counterclockwise (to the left) to decrease
the voltage output.
Note
Follow ESD guidelines when handling the S7
-1200 Potentiometer module.
