5. Wiring
The precautions and wiring method for making connection to external devices are as
given below.
5.1 Wiring instructions
Inorder for the A1S68DAV/DAI to realize its optimum performance, and to ensure reliable
system operation, the external wiring must have minimum susceptibility to noise.
The following cautions therefore apply when configuring the external wiring of the
A1S68DAV/DAI.
(1) Do not bundle the external wiring together with main circuit or high-voltage lines, or
load-bearing wires other than those of the PLC.
This will increase susceptibility to noise and the effects of surges and induction.
(2) Ground the shielding of shielded wires and shielded cables at one point.
5.2 Module connection example
(1) An example of the wiring to external devices in the case of an A1S68DAV is shown
below.
*1: Use two-core shielded wiring (twisted).
*2: If noise or ripple is generated by the external wiring, connect a 0.1 to 0.47μF (25V or
more voltage resistance parts) capacitor to the input terminal of the external device.
