• With voltage
input
Input field device
Notes:
• When using current input, connect between current input terminal (e.g., I0, I1, I2, I3) and voltage input
terminal (e.g., V0, V1, V2, V3).
• The voltage and current range cannot be used on the same channel at one time.
The terminals of the unused range should be left open.
• Use the 24 V terminal of the input terminal or the expansion power supply connector for the A/D converter
board power supply.
• Refer to page 61, "6) Wiring for I/O terminals", for the wiring.
• To prevent electric and magnetic interference, use shielded twisted-cable (two-core type) for input
terminals.
• Keep the main circuit wiring away from high voltage lines. Do not bundle signal cables and high voltage
lines together.
• The shielded cable should be grounded to the FG (frame ground) terminal of A/D converter board.
Depending on the noise conditions, if might be better to ground the cable at the input field device side.
