Installation Instructions
Before installation, it is necessary to ensure that the associated equipment of the PLC host and the
terminal of the BD module are reliably powered off.
This module comes with two standard terminals; please plug the terminals into the module
terminals after wiring. Confirm the installation of host, module and wiring are correct and then
power on.
Caution
：
1)
When using current output, make sure that the external load resistance is ≤500Ω. If the
external load resistance> 500Ω, the output current will be lower than normal;
2)
To install the function expansion board firmly and fix it on the PLC, poor contact may cause
malfunction;
3)
The fastening torque is 0.3-0.6N.m. Firmly screw down to prevent malfunctions;
4)
The PLC main unit of the LX3V can only use one BD board. Don’t try to use two or more BD
boards (these BD boards will not work);
5)
When mounting module to PLC, all the lights are blinking after power ON PLC, it means this PLC
can’t support it, please purchase new PLC.
Warnings
：
Cut off the electricity before installation/disassembly of the unit or connection of wires onto the
unit, to prevent electric shock or product damage.

Features of LX3V-2TC2DAI-BD
1)
It could use LX3V-2TC2DAI-BD to add 2 analog input points and 2 current output points. It is
internally installed in the top of PLC, thus it is not necessary to change the PLC’s installation
area.
2)
The analog digital conversion of LX3V-2TC2DAI-BD module is thermocouple input (K or J type),
current output (4~20mA), and the data of all the channels after conversion are stored inside a
special digital memory, but the converted characteristics of the analog data cannot be adjusted.
The allocation of the relevant channel addresses is in the following table.
