Wiring
1. Use 22-16 AWG (1.5mm) shielded cable for analog I/O wiring. The specification of the
terminal is shown in the figure on the left hand side. The ELC terminal screws should be
tightened to 1.95 kg-cm (1.7 in-lbs) and please use 60/75°C copper conductor only.
2. Analog signal wires and power supply wires should not be run in the same multi-wire cable
or conduit.

Note 1
: For current inputs, jumper the V+ and I+ terminals.
Note 3
: Connect FG to ground to reduce electrical noise.
Note 4
: Connect
terminal of the power supply and
terminal of analog input module to
a system earth ground point.
Note 5
: A 0.1~0.47uf 25V capacitor can be used to further reduce the effects of electrical noise
on the analog input.
Warning:
DO NOT wire to the No function terminals.
