Allen-Bradley 1745-PT1 Industrial Control Module

Allen-Bradley 1745-PT1 Pocket Programmer is a handheld programming terminal for the SLC-100 and SLC-150 programmable logic controllers in Rockwell Automation’s SLC family. It enables on-site programming of memory and viewing or editing basic ladder logic and data blocks for legacy AB systems, using a compact form factor designed for field service. The unit features an LED display with seven-segment readouts for immediate status information, and it draws operating power from the connected processor unit rather than from a separate power source. A compatible programming cable is used to connect the PT1 to the CPU or programming port, allowing loading, viewing, and troubleshooting of program data on SLC-100/150 controllers. Operational range reflects typical field use: 0 to 50 C ambient operating temperature, with storage and transport in -40 to 85 C. As part of the SLC-100/150 pocket programmer ecosystem, the PT1 is a common tool for commissioning, servicing, and memory checks on older Allen-Bradley PLC installations.
