All-in-One Compact I/O
Integrated coupler + I/O. Space-saving. Multi-protocol.
RS Series offers all-in-one compact I/O modules with integrated coupler and I/O in a single housing. Space-saving design with multi-protocol support.
Use RS Series when the required I/O mix fits an integrated coupler-plus-I/O model and cabinet space is more important than module-by-module expansion. Confirm the exact protocol, channel composition, terminal arrangement and mounting envelope in the RS catalog before ordering.
Best suited for
- Compact DIN-rail cabinets with a stable, known channel count
- Machines that prefer an integrated coupler and I/O housing
Not recommended for
- Projects requiring frequent addition of mixed expansion modules
- Machine-mounted IP67 locations
Selection steps
- Confirm the fixed I/O mix — Select the integrated model only after DI/DO and any special channels are frozen.
- Verify protocol — Match the PLC network to the exact RS communication variant.
- Check cabinet envelope — Validate width, wiring bend radius and service clearance against the catalog.
- Reserve expansion strategy — If future channel growth is uncertain, compare the modular RB architecture before release.
Evidence and verification
RS integrated architecture, protocol variants and installation information are checked against the published RS catalog.
