Publication 1771ĆIN043B-EN-P - July 2002

The following tables and wiring diagrams

represent wiring for a flowmeter input (F0),

a gate input (G0), and an output (O0).

See the wiring-arm diagram for the terminals

used in wiring F1-F3, G1-G3, and O1-O3.

Make Connections to the

Field Wiring Arm

Connect your I/O devices to the 40-terminal

field wiring arm (cat. no. 1771-WN) shipped

with the CFM module.

Remove power

to all I/O devices before you

connect them to the wiring arm.

Failure to remove power from

your I/O devices could cause:

• injury

• damage to module circuitry

• equipment damage due to

unexpected operation

!

ATTENTION

Actual wiring runs in this direction.

The sensor cable must be shielded. The shield:

• must extend the length of the cable, but be

connected only at the 1771 I/O chassis

• must extend up to the point of termination

Important: The shield should extend to the

termination point, exposing just enough

cable to adequately terminate the inner

conductors. Use heat shrink or another

suitable insulation where the wire exits

the cable jacket.

If multiple power sources are used, do not exceed the

specified isolation voltage.
