WECON PLC Extend board LX3V-2PT2DA-BD

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

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

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