Terminal block adapter for CS1 rack wiring
The Omron CS1W-AT115 is a terminal block conversion unit that adapts the CS1 Series PLC backplane connector to a field-wiring terminal block, letting you land field wiring without disconnecting the ribbon cable at the module face.
The CS1W-AT115 carries an EOL Hot lifecycle status, meaning Omron has discontinued production and the part is no longer available through the factory channel — supply is limited to existing distributor stocks and the independent surplus market. Buyers should confirm the BOM position and mating half before committing.
Compatibility and fit
Designed for the CS1 Series PLC platform — it mounts between the I/O module and the backplane connector, converting the module's connector to a screw-terminal strip for easier field wiring. Compatibility with CS1D or CS1G CPUs is not documented; verify against the specific rack and module combination.
