(c) Precautions for external wiring
To obtain the maximum performance from the functions of the D/A converter module and improve the system
reliability, an external wiring with high durability against noise is required. Precautions for external wiring are as
follows:
• Use separate cables for the AC control circuit and the external output signals of the D/A converter module
to avoid the influence of the AC side surges or induction.
• Do not install cables together with the main circuit lines, high voltage lines, or power cables for equipment
other than the programmable controller. Noise, surges, or induction may affect the system.
• Ground the shielded wires or shielded cables at one point on the programmable controller side. However,
depending on the external noise conditions, it may be better to ground them externally.
(d) External wiring
The following describes the external wiring.
• For the voltage output
D/A
conversion
*1 For the wire, use the shielded twisted pair cable.
*2 If there is noise or ripples in the external wiring, connect a 0.1 to 0.47µF capacitor (25V or higher voltage-resistant
product) to the input terminal of the external device.
• For the current output
D/A
conversion
*1 For the wire, use the shielded twisted pair cable.
*2 If there is noise or ripples in the external wiring, connect a 0.1 to 0.47µF capacitor (25V or higher voltage-resistant
product) to the input terminal of the external device.
