Installation Instructions
ProcessLogix Pulse Input Module
Catalog no. 1757-PIM
This document tells you how to install the 1757-PIM (Pulse Input Module) into the
ProcessLogix™ System. For more specific information regarding the placement of
the 1757-PIM in non-redundant and redundant configurations, refer to the
ProcessLogix System Planning Guide in Knowledge Builder.
What is the Pulse Input Module?
The 1757-PIM (Pulse Input Module) is a new addition to the ProcessLogix Rack
I/O family.
The 1757-PIM is a single-wide I/O module that serves as the interface board
between the ProcessLogix controller and field transducers that provide pulse inputs.
Typically the 1757-PIM might be used to accept pulse inputs from:
• tachometers, to determine required speeds of rotation for motors, fans and
pumps
• flowmeters, to determine totalized process flows such as inputs to batch
dosing operations
The 1757-PIM provides up to eight input channels and two output channels. Each
of the eight channels has a 32-bit counter to perform pulse counting and frequency
calculation for signals up to 100 KHz. Six of the eight channels also have a second
32-bit timer counter for pulse period and pulse width measurements. The
remaining channels provide pulse counting and frequency calculations and have
associated outputs that can be used for fast cut-off applications. The 1757-PIM
provides channel-to-channel and terminal-to-backplane isolation.
The 1757-PIM uses the standard 36-pin terminal block and interfaces directly to
single-ended devices. The threshold level for each channel is software configurable
and selections are either LOW (approx. 3.25V typical) or HIGH (approx. 8.80V
typical) for a high-level voltage level. The 1757-PIM interfaces directly to 5 to 24V
signal values.

Installing the Module
Follow the procedure below to install the module.
Making Field Wiring Connections
Refer to the following pinout/wiring diagram to wire the module.
This input module permits the field-side input device (switch)
to be located on either the hot or neutral side of the source,
unless the module’s shorting bar has been installed. In this
case, the input device must be installed on the hot side of the
source.

For instance, Transmitter 0 will be connected to Pins 1, 3 and 5 where:
Pin 1 is the Signal
•
Pin 3 is the Signal Common
•
Pin 5 is the Chassis Ground Shield Connection
•
The Output Channel 0 will connect to Pins 33 and 35 and Output Channel 1 will connect to Pins 34
and 36.
