Wire the H-LINK cable as short as possible, keep a distance of 6 inches or more with a Power Supply
cable and do not wire them in parallel (However in cross line is possible).
If the cables have to run in parallel, insert one of them into a metal conduit tube (with one end earthed) or,
perform a procedure to prevent noise such as using shielded cable for H-LINK (with one end earthed).
Connection with External Device
*1) External input circuit is 24VDC applicable by using the pull-up resistor in CCCA01. The maximum
allowable amount of current from the CCCA01 is 5mA. Pulse duration and pulse interval need to
be set to 500ms or longer when using external input with pulse input.

- Rated voltage: 24VDC
- Rated current: 40mA or less
*3) Turn ON SW9 “OUTPUT” setting when using external output using a wet contact setting (item 3).
*4) Terminals IN4-IN8 will not be used in this product.
(6) Attach the top cover after completing the wiring connection. When attaching the top cover, ensure that
the direction of the top cover is correct as shown in Figure 7.7.
