The Mitsubishi RX40NC6S-TS is a 16-point, single-wiring DC input module sitting in the PLC Expansion Modules class for the MELSEC iQ-R rack, so it drops onto the same expansion base as the rest of the iQ-R IO family. It is a pure digital-input slice — no relay, no analog, no communications bridge — intended to extend point count on an iQ-R CPU already in the panel.
Sourcing posture and lifecycle
Lifecycle stage is recorded as current, which means the BOM line is specified against an active part and is sourced to order rather than hunted through the last-time-buy channel. For a procurement buyer that resolves the standard calculation: quote against the RFQ at the quantity on the BOM, expect a manufacturer-channel lead consistent with current iQ-R IO, and skip the obsolete/surplus workarounds.
