Overview
This manual explains the installation and operation of the
7551 LDT Interface Module.
Utilizing licensed Allen-Bradley SLC 500™ I/O inter-
face technology, the one slot 7551 LDT Interface Module
accepts one transducer input and plugs directly into the
A-B SLC 500 rack. Communicating through I/O
registers assigned to the slot, the module supplies abso-
lute position and velocity data to A-B SLC™ processors
from AMCI, Balluf or Temposonics™ II magnetostric-
tive linear displacement transducers (LDTs).
Front Panel Description
Two LEDs on the front panel shows the modules'
operating status.
LDT
INTERFACE
7551
The transducer input connector, located behind the
module door, accepts the 8 pin Phoenix connector
(AMCI Part # MS-8) from the transducer cable. The
transducer cable wiring diagram is shown under "Cable
Installation". The 7551 uses the following transducers:
•
AMCI LHT Series LDT
•
MTS Temposonics II LDT with DPM or RPM
Personality Modules
•
Balluff LDT with 'K2' output / power supply
option.
The 7551 module requires an external ±15 Vdc supply
for LDT operation. Power supply current rating is
based on the actual LDT.

RUN - This green LED is on
when the module is operational.
FAULT - This red LED is
blinking when there is a trans-
ducer fault, or on when there is a
module fault. There are four
major causes of a transducer
fault.
•
Broken transducer cable.
•
Non-compatible transducer.
•
Improperly wired transducer
cable.
•
Faulty transducer.

ADVANCED MICRO CONTROLS, INC. warrants that all equipment manufactured by it will be free from defects, under normal use, in materials and workmanship for a period of [1] year. Within this warranty period, AMCI shall, at its option, repair or replace, free of charge, any equipment covered by this warranty which is returned, shipping charges prepaid, within one year from date of invoice, and which upon examination proves to be defective in material or workmanship and not caused by accident, misuse, neglect, alteration, improper installation or improper testing. - Page 9 Please refer to page 3 of the manual for wiring information, and note that pin 1 is located at the bottom of the connector when it is plugged into the module. AMCI, Balluff, and Temposonic II transducers all require an external +15Vdc to operate. The Temposonic LP and LH transducers require an external +15Vdc to +24Vdc to operate.
