standard lengths (005=0.5m, 010=1.0m, 025=2.5m,
050=5.0m). Custom length cables are also available.
Á Shield terminals on AIFM are connected to pre-wired
cable shield through D-shell housing.

Notes:
This diagram illustrates using two wire current
transmitters (with a common power supply) with the
1756-IF16 running in differential mode and using
1492-AIFM16-F-3 interface module. The power
supply is connected to the V+ and RTN terminal of
the IFM. Each transmitter receives power from the
+VxF fused output terminal of the IFM and the
current input feeds into the corresponding IN-x
terminal.
Only the EVEN numbered(IN-0,IN-2, etc) terminals
are used. All ODD numbered terminals must be
jumpered to the RTN terminal on the IFM module.
