AS16AM10N-A is a 16-point high-density NPN digital input module for Delta AS series PLCs, supporting 24VDC sink input with 2500V AC optical isolation and fast response. The high-density design saves cabinet space and reduces wiring compared with using multiple low-point modules. Each channel has an LED indicator for real-time status monitoring and troubleshooting. It captures signals from proximity, photoelectric, limit and safety sensors. It is widely used in medium and large systems including production lines, machine tools, logistics equipment, printing machines and automotive assembly lines. It provides stable input acquisition even in strong electromagnetic environments, supporting position detection, safety interlock, status feedback and sequential control to improve system reliability and integration.
