Mitsubishi KM878240G02 Elevator Decoder — Replacement for KM878240G01

Mitsubishi Electric · Elevator Decoder · Car Position Board · In Stock

The KM878240G02 is a Mitsubishi Electric elevator decoder / car position board used in Mitsubishi elevator control systems to translate floor-level signals, door-zone references and leveling switch feedback into the calls the main controller expects. The board is fully cross-compatible with the legacy KM878240G01 and is the recommended drop-in for field service on NEXIEZ, GPS-III and earlier Mitsubishi traction elevator platforms. KOEED stocks the KM878240G02 alongside the broader elevator parts catalog so service companies, modernization contractors and building maintenance teams can quote a full BOM in a single email.

Not sure if this decoder fits your elevator? Send us the elevator model number, controller series (e.g. NEXIEZ, GPS-III, E-Series) and the serial plate of the failed board, and our elevator parts desk will confirm compatibility within one business day.

Key Specifications

Datasheet Highlights

• Drop-in upgrade over G01 revision — the KM878240G02 supersedes the older KM878240G01 with refined input filtering, eliminating the intermittent floor-skip faults reported on early production G01 boards in high-traffic buildings.
• Car position decoding for NEXIEZ / GPS-III — converts floor-magnet or shaft-encoder pulses into clean floor calls for the main controller, supporting both single-deck and double-deck Mitsubishi car configurations.
• Door-zone and leveling signal conditioning — the decoder aggregates door-zone, leveling and re-leveling switch inputs so the controller can manage accurate stops at the floor landing without bounce or overshoot.
• Industrial-grade Mitsubishi build quality — conformal-coated PCB, robust connectors and conservative component derating typical of the KM8xxxxxx family used across Mitsubishi traction and hydraulic elevators worldwide.
• 90-day limited warranty — standard KOEED warranty on EOL and hard-to-find elevator boards, with worldwide shipping and DHL / FedEx / UPS options on request.

Typical Applications

• Elevator service companies and maintenance contractors — replacing a failed KM878240G01 / G02 in the field after floor-call errors, leveling drift or car-position lamp faults.
• Modernization of older Mitsubishi elevator systems — restoring NEXIEZ and GPS-III controllers to reliable operation when the original decoder is obsolete or no longer available from the OEM. Browse the full elevator modernization catalog for related boards, drives and door operators.
• Building owners managing multi-elevator portfolios — keeping a small on-hand stock of KM878240G02 boards to minimize tenant-impacting downtime when one car goes out of service.
• Cross-OEM service and decoders from other brands — service shops that also maintain Kone, Otis, Schindler and Hitachi elevators can source comparable decoder boards from KOEED — our nine-brand matrix covers Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic and KEYENCE, plus a deep elevator parts inventory across the major traction OEMs.
• Refurbished and exported traction elevators — resellers shipping used Mitsubishi cars overseas where the local aftermarket cannot supply authentic KM-series boards.
• EOL / hard-to-find elevator spares — read the elevator decoder guide for a quick reference of compatible Mitsubishi, Kone, Otis, Schindler and Hitachi decoder boards.
