FL1B-J2B2
The illustration above shows an example of four-wire current
measurement and two-wire voltage measurement.
Connecting a two-wire sensor to the FL1B-J2B2
Wire up the two-wire sensor's connecting wires as follows:
1. Connect the sensor's output to connection U (0 ... 10 V
voltage measurement) or to connection I (0 ... 20 mA cur-
rent measurement) of the FL1B-J2B2 module.
2. Connect the plus connector on the sensor to the 24 V
supply voltage (L+).
Connect the ground connection on the sensor to the corre-
sponding M input (M1 or M2) on the FL1B-J2B2 module.
