*1 Use a two-core twisted shield line for the power cable.

*2 Indicates the AJ65SBT-64AD input resistor.

*3 For the current input, be sure to connect t he (V+) and (I+) terminals.

*4 When noise or ripple occurs with the externa l cable, connect a condenser with

about 0.1 to 0.47µF (25V or higher voltage-res istant product) between the terminal

V and COM.

*5 Always perform grounding for FG1. When ther e is a lot of noise, it may be better

ground AG as well.

If the grounding wiring (grounding yes/no) is changed after the of fset and gain are

set, perform the setting of the offset/gain values again.

POINT

A/D conversion values are fluctuated by self -heating within approx. 30 minutes after

power is turned ON.

4.9 Maintenance and Inspection

There are no special inspection items for the AJ65SBT-64AD module, but follow the

inspections items describes in the PLC CPU User 's Manual so that the system can

always be used in the best condition.
