Mitsubishi RX40C7-TS Mitsubishi MELSEC RX Input Modules

Razz Middle East supplies Mitsubishi Electric MELSEC RX-series input modules in Saudi Arabia, sourced to order against the exact model code. These are the digital input cards that slot into a MELSEC rack and bring field contacts, pushbuttons, limit switches and sensor outputs into the controller. Items are ordered by the complete code and delivered duty-paid, normally within three weeks.

About Mitsubishi MELSEC RX Input Modules

Codes such as RX40C7 and RX42C4 identify a module by its point count, its input voltage type and its terminal arrangement. The digits after RX separate the smaller-point modules from the high-density ones, which use a connector rather than a screw terminal block and need a matching pre-wired cable or a terminal interface unit ordered separately. A TS suffix marks a spring-clamp terminal version, which is mechanically and electrically the same input circuit but is wired without screws; it is a different order and cannot be created by swapping a terminal block. Input modules are specified by whether they accept DC or AC field signals, by their response time, and by whether they are wired as positive or negative common, and that common arrangement has to match the field wiring already installed. RX modules belong to the MELSEC iQ-R generation, and they are not interchangeable with the earlier Q-series or with the compact FX line, so the rack generation determines what will fit.

Mitsubishi MELSEC RX Input Modules in Saudi Arabia

MELSEC iQ-R racks are found in Saudi plants that run machinery and packaged systems of Japanese origin, and in process and utility panels where the controller was specified for a long service life. Typical settings are packaging, plastics, food and beverage and building-materials lines around Riyadh, Jeddah and Dammam, water treatment and pumping control panels, and materials handling in cement and mining operations. Input modules are a common spare because they sit at the interface with the field: a shorted sensor cable, a wet terminal box or an induced surge on a long run damages an input card before it damages the CPU. Sites with outdoor field wiring in the Eastern Province and along the coasts see this more often, since heat, humidity and dust degrade field terminations. Control voltage is normally 24 V DC, distribution is 380/400 V at 60 Hz, and imported equipment must satisfy the applicable SASO conformity requirements.

Ordering and lead time

Send the full model code from the module face, including any suffix, because the spring-clamp and screw-terminal versions and the connector and terminal-block versions are separate parts. Name the rack and CPU as well, since a module from a different MELSEC generation will not fit the base even where the code looks similar. Confirm the input voltage type and the common arrangement used in the existing wiring. For high-density modules, say whether you also need the pre-wired connector cable or terminal interface unit, as these are ordered separately and are frequently missed. If the module is being replaced after a field fault, it is worth checking the field wiring before fitting the new card. Items are sourced to order and delivered duty-paid, with a normal lead time of three weeks.
