Upgrade legacy installations with the Mitsubishi Electric ERNT-AQTY41 terminal block adapter, purpose-built to transition from AY41 wiring to QY41 modules in MELSEC Q Series PLC systems. Designed for control cabinet retrofits, it enables fast migration while keeping existing field wiring intact and minimizing downtime.
This upgrade tool maps terminals one-to-one between AY41 and QY41, delivering a secure mechanical fit and reliable signal continuity without rewiring. Robust contacts and precise tolerances support industrial environments, while CE and UL/cUL compliance align with common plant standards. Compact dimensions simplify routing in dense I/O racks.
Ideal for brownfield modernization and scheduled maintenance, the ERNT-AQTY41 streamlines I/O replacement to reduce installation risk and total cost of ownership, and it is supplied with a 1-year warranty for added assurance during your upgrade cycle.
