SLC 500

The Allen-Bradley 1746-P1 is a rack-mount power supply for the SLC 500 programmable controller family. It accepts 120/240V AC input and provides 2A at 5V DC and 0.46A at 24V DC backplane power, along with a 200 mA user-power output for external sensors.

The Allen‑Bradley 1746‑NI4 is a 4‑channel analog input module for the SLC 500 programmable controller family. It accepts voltage (±10V DC) or current (±20mA) signals from field devices such as pressure transmitters, temperature sensors, and level transducers, converting them into digital values for use in the PLC's control program.

The Allen‑Bradley 1747‑L542 is an SLC 5/04 modular processor from Rockwell Automation's SLC 500 family, offering 32K words of user memory and supporting up to 4,096 discrete I/O points. As the mid-range model in the 5/04 series, it features built-in Data Highway Plus (DH+) and RS-232 communication ports, enabling high-speed peer-to-peer messaging with PLC-5, SLC, and ControlLogix processors.

he Allen‑Bradley 1747‑KFC15 is a ControlNet RS‑232 Interface Module for the SLC 500 platform that acts as a DF1‑to‑ControlNet bridge. It connects SLC 5/03, 5/04, or 5/05 processors to a ControlNet network via the processor's Channel 0 serial port, enabling deterministic data exchange with ControlNet‑capable HMIs, drives, and other controllers.

The Allen‑Bradley 1747‑L541 is an SLC 5/04 modular processor from Rockwell Automation's SLC 500 family, offering 16K words of user memory and supporting up to 4,096 discrete I/O points. It features built-in Data Highway Plus (DH+) and RS-232 communication ports, enabling high-speed peer-to-peer messaging with PLC-2, PLC-5, and ControlLogix processors.
