LDT Interface Card
High Resolution LDT Interface
Module Provides Continuous
Linear Position Input to A-B
SLC500 I/O Chassis
The Series 1746L LDT Interface Card is a magne-
tostrictive linear displacement transducer (LDT)
based unit that incorporates Allen-Bradley licensed
technology for complete compatibility with A-B
Series 1746 I/O chassis. The unit monitors machine
position and delivers continuous absolute position
data to the SLC processor in inches to 0.001" or in
millimeters to 0.01mm and velocity data. This high
resolution is accomplished without the need for
recirculations for improved system response time.
The Series 1746L is available in two versions to
accommodate one LDT or two LDT’s. All power
for the LDT’s is supplied directly from the 1746
Interface Module. Other features include: position
freeze, movement fault detection and program-
mable over travel limits for use in pressrooms and
general purpose industrial automation.
The 1746L LDT Interface Card is suitable for use
with many LDT inputs, including Gemco Series 951
Quick-Stik II
™
and Series 952 BlueOx
™
LDT’s.
