manipulate values representing temperature, pressure, rotational speed,
light intensity, and position.
A wiring arm (cat. no. 1771-WB) accompanies the module. It acts as a
terminal strip for input connections. The wiring arm pivots on the I/O
chassis to connect with terminals on the front of the input module. Thus,
the wiring arm lets you quickly connect or disconnect your input wiring
when inserting or removing the input module from the I/O chassis.
The input module meets the requirements of the Instrument Society of
America, Standard S50.1 (1975), “Compatibility of Analog Signals for
Electronic Industrial Process Instruments.”
The input module supports eight single-ended input channels. All eight
channels have the same voltage or current range that you select when
ordering the module. The range is factory set and calibrated.

When ordering 1771-IE modules, place the order code as a suffix to the
catalog number. For example, 1771-IE-04.
You can change from a voltage range to the equivalent current range and
vice versa within limited catagories. For example, from the above table
you can switch from a range of (1 to 5 VDC) to (4 to 20 mA) or (0 to 5
VDC) to (0 to 20 mA) without recalibrating.
Analog input modules communicate with a programmable controller by
block transfer in the following manner (Figure 2.2).
