Description
Allen-Bradley 1745-PCC SLC Personal Computer Interface Converter 12-30VDC DB25
The Allen-Bradley 1745-PCC is an SLC Personal Computer Interface Converter that connects a standard PC serial port to Allen-Bradley SLC-series programmable logic controllers. It acts as a protocol and electrical interface bridge, allowing programming software running on a PC to communicate directly with SLC-100 and SLC-150 controllers over a serial link. The converter draws its operating power from the connected SLC controller via the DIN cable, eliminating the need for a separate bench power supply in most standard (local) setups.

Applications
The 1745-PCC was the standard programming and monitoring interface for Allen-Bradley's early SLC (Small Logic Controller) product line — the SLC-100 and SLC-150 — introduced in the early-to-mid 1980s as compact, low-cost PLCs for small machine automation. The converter plugs between the PC's 25-pin serial (RS-232) port and the proprietary DIN connector on the SLC controller, translating between the PC's serial interface and the controller's communication protocol. A PC running Allen-Bradley's DOS-based programming software (such as APS or AI Series) would use this cable to upload and download ladder logic programs, monitor I/O status, and perform online edits. For remote installations — up to 4000 feet — the optional 1745-PCP remote power supply module was used alongside this converter. Today, the 1745-PCC is primarily sought by facilities still maintaining legacy SLC-100 or SLC-150 installations, and by industrial automation technicians or collectors working with early Allen-Bradley PLC systems.
This Allen-Bradley 1745-PCC SLC Personal Computer Interface Converter was pulled from a working industrial environment where it was previously in use. The unit has been visually inspected and photographed. The white plastic housing is in good condition with minor surface scuffs typical of used industrial equipment. Both the DB25 ribbon cable and the round DIN-style cable are present and intact, with the DB25 connector showing some light dust in the pin housing — pins appear undamaged. The label is fully legible. Please view our photo set and contact us if you have any questions.
