5-1 Wiring of Analog Input Module
5-1-2 Wiring example
The analog input modules shall be wired according to the figure below, using shielded twisted pair cables.
Note 1: Unused channels shall basically be short-circuited.
Note 2: Ground shielding wires at one point on the PC side (class D grounding). However, when shielding wires had better
be grounded on the external device side due to the condition of external noise, their ends on the module side must be
open. For grounding, NC terminals can be used as dummy termination for shielding wires. However, they must not
be used as dummy termination for other control signal cables or power cables.
Note 3: Keep signal wires that go out of this module sufficiently away from high-voltage or power cables, and avoid parallel
wiring.
Note 4: Avoid wiring the signal cables in the vicinity of load cables coming from devices other than PLC or bundling them with
such cables.
Note 5: Keep the signal cables sufficiently away from circuits where high frequencies occur, such as inverter main load circuit.
