Terminal block conversion for CS1 racks
The Omron CS1W-AT133 is a terminal block conversion unit that adapts the CS1 series PLC backplane to a screw-clamp termination field. It lets you land field wiring on a fixed terminal block rather than the I/O module's connector — useful when a module swap would otherwise disturb the wiring. Rated for the CS1 series racks, this adapter accessory keeps the machine running through module changes without pulling wires from the field. The bulk package means it ships as a single unit, not a reel or tray.
The replacement path for a CS1 rack is typically a migration to the CJ or NX series, which uses a different backplane and terminal-block footprint. Confirm the rack model before committing the BOM line.
The unit mounts directly to the CS1-series backplane, converting the I/O connector to a fixed terminal block. No DIN-rail or additional bracket is required — it snaps into the rack slot and the field wiring lands on the screw terminals.
