The Allen‑Bradley 1791-OB16 is a discontinued 16-point sourcing DC output Block I/O module designed for Remote I/O (RIO) networks with PLC‑5 and SLC 500 controllers. It provides 24 VDC sourcing digital outputs rated 0.5 A per channel, supporting solenoids, indicators and small contactors. Featuring electrical isolation between field circuits and control logic, it supports DIN rail or panel mounting. Widely deployed for distributed discrete control on legacy assembly lines, material handling and packaging equipment.

1746‑RT35 is an official removable terminal block dedicated to the Allen‑Bradley 1746‑NR8 8‑channel RTD/resistance input module for SLC 500 PLC. It offers 24 terminals supporting 22–16 AWG cables with specified screw torque. Compatible with 2/3/4‑wire RTDs and resistive sensors. Operating temperature 0~60°C, IP20 cabinet use. Plug‑out design simplifies wiring maintenance for industrial temperature measurement loops on legacy SLC control systems.
