I/O Rack Installation & Removal
Before installation, confirm that the I/O power is compatible with the Series 1746L PLC LDT
Interface Module. (See Appendix A: Specifications, Power Requirements). The Series 1746L
PLC LDT Interface Module can be installed into any open slot in the A-B SLC 500 rack. Align
the module’s circuit board with the top and bottom card guides and gently slide in until it latches
securely. To remove the module, depress the top and bottom latches and slide the module out of
the rack.
NOTE: The Series 1746L has a convenient plug-in terminal strip. Therefore, the module can
be removed or replaced without rewiring the terminal strip.
LDT Installation
The 1746L is designed to use Gemco Models 951, 952 and 955 LDTs. Specifications, mounting
guidelines and outline drawings for these LDTs are available from the factory.
NOTE: The Gemco Series 1746L LDT Interface Module is compatible with other LDT inputs.
Contact the factory for details.
LDT Cable Installation
It is recommended that the LDT cable be run in a separate conduit and should be a continuous
uninterrupted length. LDT cable installation is covered in the Wiring Diagram in Appendix B of
this manual. The maximum cable length using Belden 9873 (or equivalent) is 1,000 feet.
