Allen-Bradley 1745-PCC Communication Converters

The 1745-PCC is a dedicated signal and protocol converter designed to interface personal computers with Allen-Bradley SLC 100 and SLC 150 programmable logic controller systems. Belonging to the Bulletin 1745 product line, this compact communication interface converts standard RS-422 differential signals from the SLC 100/150 controller programming port into RS-232-C serial signals compatible with standard PC serial ports.

Signal Conversion and Power Requirements

The converter enables personal computers running SLC 100/150 software to upload, download, and monitor PLC programs directly. Operating with a low power consumption of 1 W, the unit accepts an input supply voltage ranging from 12 VDC to 30 VDC. Its compact form factor makes it suitable for both temporary field diagnostic connections and permanent panel-mounted communication links.

Field Compatibility and Setup

By adapting electrical signaling between RS-422 industrial controller levels and RS-232-C computer communication standards, the 1745-PCC ensures reliable data transmission during program transfer and system monitoring. It connects between the computer's serial interface and the host SLC 100 or SLC 150 controller hardware.
