Product Description

New in original box Allen-Bradley 1785-L40B PLC-5/40 Processor Module, Series A, Firmware Rev. N. The module is identified by catalog number 1785-L40B and OEM part number 96166473 A01, as printed on the manufacturer label. The item is presented in original Allen-Bradley foam-lined packaging with the module in its original anti-static bag. The label confirms backplane requirements of 3.3 A at 5 VDC, and the listing notes that the memory cartridge is not included.

The 1785-L40B is a standard processor from the Allen-Bradley PLC-5 family, designed for installation in 1771-series I/O chassis. This platform supports 4 DH+/Remote I/O channels and a serial communication port. The PLC-5/40 designation refers to the 48K word SRAM user memory capacity. Buyers matching this catalog number for PLC-5 system maintenance, spare inventory, or replacement sourcing should verify the Series and firmware revision against their system requirements, as the PLC-5 family was discontinued by Rockwell Automation.
