Product Description
The A1SY10EU is a local I/O output module for Mitsubishi MELSEC‑A series PLCs, providing 16 relay-based digital output channels with normally open contacts. Designed for mixed-voltage applications, it supports AC and DC output control commonly referenced at 120 VAC and 24 VDC, making it suitable for interfacing with a wide range of field devices. Relay outputs provide galvanic isolation and flexibility compared to transistor outputs, and the module is intended for integration into MELSEC‑A racks as part of distributed control systems. This unit is listed as discontinued by the manufacturer but remains available through distribution channels. It carries CE conformity for industrial environments. Use cases include driving pilot lights, interposing relays, solenoids, and contactor coils within control panels where relay outputs are preferred. Package contents typically include the module only; wiring terminals and rack/backplane are part of the MELSEC‑A system. Verify load current ratings and supply specifications per system documentation when designing outputs.
