1756-IF8 Single-ended Voltage
· All terminals marked RTN are connected internally.
· For current applications, all terminals marked iRTN must be
wired to terminals marked RTN.
· A 249 Ω current loop resistor is located between IN-x and
iRTN-x terminals.
· Place additional loop devices (such as strip chart recorders) at
the A location in the current loop.
· Do not connect more than two wires to any single terminal.
· All terminals marked RTN
are connected internally.
· Terminals marked i RTN are not used for single-ended voltage
wiring.
· Do not connect more than two wires to any single terminal.
