This manual is applied to LX3V-8EY and LX3V-16EY digital output expansion modules.

1 Naming rule

Naming rule of LX3V I/O output expansion module:

  1. WECON PLC;
  2. Main model;
  3. The number of output points;
  4. Product type: E means expansion;
  5. Expansion output(Y);
  6. T: transistor, R: relay.

  1. Extension cable
  2. Input indicator light of each channel
  3. LINK: Communication indicator between PLC and expansion module
  4. Expansion module name
  5. Digital signal output terminal
  6. Extension module interface
  7. DIN rail mounting slot
  8. DIN rail hook
  9. Mounting holes (φ4.5)
NameDescriptionStatusEvent status
LINKCommunication indicator between PLC and expansion moduleFlashesNormal data transmission(normal communication)
OFFData transmission is abnormal, stopped, or failed
ONSoftware is abnormal or hardware is faulty

✎Note: Except different I/O input points, LX3V-8EY and LX3V-16EY have the same dimensions and the same other functions.

Crimp terminations

  1. Please use crimp terminals as indicated on the graph.
  2. The tightening torque should be applied 5 to 8 Kg.cm.
  3. Other terminals should be empty but only wiring terminals mention in this manual.

4 Instructions

The I/O output points on the module are named from the next Y point, using the points on the host as endpoints. For example:

  1. If the host is LX3V-1212MR-A and there are 12 output points (Y0 to Y7, Y10 to Y13).
  2. If you expand an LX3V-16EY module on the host , the Y points defined in the module on the host computer are X20 to X27 and X30 to X37. 
  3. If you expand multiple I/O output point modules on the host, the I/Os on the module will be named in the same order.

✎Note: When adding IO expansion modules to the host, in principle, the number of all output points Y must not exceed 256 points. When adding IO expansion modules to the host, if the host needs to connect multiple IO modules, it is recommended to add a separate power supply board to the module for power supply.

As shown in the example above, it is LX3V-3624MT with two LX3V-16EY modules and one LX3V-4DA module. The host has 24 output points Y: Y0 to Y7, Y10 to Y17, Y20 to Y27. The output point in the module ① called by host are Y30 to Y37 and Y40 to Y47, and the output points in the module ③ called by host are Y50 to Y57 and Y60 to Y67.
