WECON PLC Extend Board LX3V-2AD2DA

1). LX3V-2AD2DA-BD module equips with 2 channels analog input and 2 channels analog output. This module will be mounted in the PLC.

2). The input current of LX3V-2AD2DA-BD module between 4 to 20mA, and the digital value will be saved in special system address, but the numerical relationship between input and

output value can not be changed.

2. Mounting instruction

Make sure to power off the PLC before mounting the 2AD2DA module.and remove the top cover of PLC, screwed to the PLC.

Caution: ①When output current, make sure that the load resistance should be less than 500Ω, otherwise the output will be lower.

②The function expansion board installed securely, and fixed on the PLC, poor contact will result in failure.

③Fixed extension board and PLC capped tightening torque is 0.3 ~ 0.6N.m

Warring: ①Make sure to power off the PLC before mounting or removing the BD module.and put the cover in right place.

②After completing the installation and wiring, please change the PLC capped tightening before turning the power.
