What the part is
The Omron CS1W-AD041-V1 is a 4-channel analog input module for the CS Series PLC rack, sliding onto the CS1W backplane with screw terminations on the field side. It belongs to the CS1W I/O family and reads analog signals into a CS1 CPU.
Where it slots in
Mounts on the CS1W backplane next to the CPU and other CS1W I/O; the field wiring lands on screw terminals per channel. Operating range is 0 to 55 °C, which is the cabinet envelope a CS1 rack expects in a typical control panel. Approval set is CE, cULus, Lloyd, and NK — Lloyd and NK are the marine class society marks, so panels headed for shipboard or offshore cabinets have a documented paper trail on this part.
