The 1746-A4 belongs to the Allen-Bradley 1746 SLC modular system. Compatibility depends on the exact processor or adapter, system power supply, module power requirements, slot arrangement, series and overall architecture. A 1746 catalog-number prefix alone does not confirm compatibility.
The 1746-A4 is included within the SLC 500 product family documentation addressing applicable Australian radiocommunications and EMC requirements, including EN 61000-6-4 for industrial environments. Regulatory markings must be verified against the exact product series and label.
A larger SLC chassis or newer platform must not be described as a direct replacement. Migration can require mechanical, electrical, I/O, communication and program changes.
For a configuration-checked quotation, provide:
It is a four-slot modular chassis in the Allen-Bradley 1746 SLC system.
The chassis provides four numbered module slots.
The applicable modular power supply mounts at the left side of the chassis rather than occupying a numbered module slot.
Compatibility depends on the exact controller or adapter, series, power requirements and system architecture.
Yes. Its documented discontinued date is March 31, 2024.
The replacement category is “No planned RA replacement.” Any migration requires an engineering review.
