MPN: A1SX42 — industrial control spare part, in stock at TGK Parts.
The A1SX42 is the 32-point DC input module of the Mitsubishi MELSEC-A series — the high-density input card for machine I/O. Input circuits die from field miswiring (AC landed on DC commons) and opto-coupler aging; both are invisible without a point-by-point test, which is exactly what we run on every unit.
Obsolete but still in demand on thousands of running A-series lines; tested used and NOS stock.
