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.","metaTitle":"Omron CS1W-AT133 Terminal Block Conversion Unit","metaDescription":"Omron CS1W-AT133 terminal block conversion unit for CS1 series PLCs.
