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.
