Note:
*1 Connect the terminal FG to the ground terminal of a programmable controller grounded
with a resistance of 100Ω or less (Class D grounding). If the programmable controller is
not equipped with a ground terminal, connect the terminal FG directly to a ground with the
resistance of 100Ω or less (Class D grounding).
2 ) Two-pair Wiring
Terminating
resistor
330Ω
Terminating
resistor
330Ω
Note:
*1 Connect the terminal FG to the ground terminal of a programmable controller grounded
with a resistance of 100Ω or less (Class D grounding). If the programmable controller is
not equipped with a ground terminal, connect the terminal FG directly to a ground with the
