4.7 Wiring 

Precautions when wiring the AJ65BT-64DAV/DAI and how to wire to the external devices are 
explained. 
 

4.7.1 

Precautions when wiring 

To obtain maximum performance from the functions of AJ65BT-64DAV/DAI and improve the system 
reliability, an external wiring with high durability against noise is required. 
The precautions performing external wiring for the AJ65BT-64DAV/DAI are shown below: 
(1)  Use separate cables for the AC and AJ65BT-64DAV/DAI external input signals, in order not to be 

affected by the AC side surge or conductivity. 

(2)  Do not bunch the control wires or load cables from other than the programmable controller with 

the wires to the module, or install them close to each other. Doing this makes the wiring easy to 
accept the noise, surge or induction effects. 

(3)  Perform a one-point grounding for the shielded line or the shield of the shielded cable. 
 
 

4.7.2 

Wiring between the AJ65BT-64DAV/DAI and external devices 

 
(1)  Wiring example of the AJ65BT-64DAV and external devices is shown in Figure 4.1. 
 

 

*1  Use a two-core twist shielded line for the wiring. 
*2  When noise or ripple generates within the external wiring, connect a condenser with about 

0.1 to 0.47

μ

F (25V or higher voltage-resistant product) to the input terminal of the external 

device.
