CPM1A Expansion I/O Unit Wiring

40-point I/O Units (CPM1A-40ED@@)
Input Wiring
To enable using the analog I/O under optimal conditions, be careful of the fol-
lowing points for noise reduction.
• Use 2-conductor shielded twisted-pair cable for the I/O wiring, and do not
connect the shield.
• Wire I/O lines apart from power lines (AC power supply lines, three-phase
power lines, etc.), and do not place them in the same duct.
• If noise is received from power supply lines (e.g., when sharing a power
supply with electric welding machines or electric charging devices, or
when near a high-frequency source), insert a noise filter in the power sup-
ply input section.
