*2 Indicates the AJ65SBT-64AD input resistor.

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

*4 When noise or ripple occurs with the external cable, connect a condenser with about 0.1 to 0.47µF (25V or higher voltage-resistant product) between the terminal V and COM.

*5 Always perform grounding for FG1. When there is a lot of noise, it may be better ground AG as well.

If the grounding wiring (grounding yes/no) is changed after the offset 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.
