Installation and wiring
Various special blocks controlled by the FROM/TO commands, such as the analog input blocks
high-speed counter blocks, etc. can be connected to the LX3V programmable controller (MPU), or
connected to the right side of the other extension blocks or units. Up to 16 special blocks can be connected
to a single MPU in the numeric order of No. 0 to No.15.

WIRING:
The terminal layout shown below may differ from the actual layout. For the correct terminal
layout, refer to section 2 External Dimensions and Parts.
Figure 3-2
*1: Use a twisted pair shielded cable for the analog output. This cable should be wired away from
power lines or any other lines which could induce noise.
*2: Apply 1-point grounding at the load side of the output cable (class 3 grounding: 100Ω or less).
*3: If electrical noise or a voltage ripple exists at the output, connect a smoothing capacitor of 0.1 to
0.47uF, 25V.
*4: Connect the
terminal on the LX3V-4DA with the
terminal on the MPU of the
programmable controller.
*5: Shorting the voltage output terminal or connecting the current output load to the voltage output
terminal may damage the LX3V-4DA.
*6: The 24V DC service power of the programmable controller can also be used.
