Connect your I/O devices to the cat. no. 1771-WG wiring arm shipped
with the module. Attach the wiring arm to the pivot bar at the bottom of
the I/O chassis. It pivots upward and connects with the module so you can
install or remove the module without disconnecting the wires.
Input connections for the 1771-IFE with single-ended inputs are shown in
Figure 2.2 and Figure 2.3. Input connections for the 1771-IFE with
differential inputs are shown in Figure 2.4 and Figure 2.5.
Recommended maximum cable length for voltage-mode input devices is
50 feet. This recommendation is based on considerations of signal
degradation and electrical noise immunity in typical industrial
environments. Cable length for current-mode input devices need not be as
restrictive because analog signals from these devices are less sensitive to
electrical noise interference.
The 1771-IFE module is shipped from the factory set for a 1 to 5V DC
voltage input. Refer to “Changing Your Module’s Configuration”on page
2-9 for other combinations of current and voltage inputs.
