Product Description
The A1SX10 is a local AC digital input module for MELSEC‑A series PLC systems, providing 16 isolated digital input channels for monitoring field devices operating at 100 to 120 Vac. Designed for reliable acquisition of AC signals, it supports stable operation in industrial environments and integrates on the A-series I/O backplane as a local unit. With low input current draw per point and terminal row wiring, it simplifies installation while maintaining signal integrity for control and data acquisition tasks. The module is suitable for applications requiring precise detection of AC states across machinery, process equipment, and facility systems. It has been discontinued by the manufacturer, but remains widely used in legacy MELSEC‑A installations and compatible service replacements. Package contents typically include the input module only; field connectors and accessories are system-dependent. Engineers should verify slot compatibility and system grounding practices within A-series racks for optimal performance.
