16-Channel 24V DC Digital Input, High-Density Design:Provides 16 independent digital input points for standard 24V DC signals, ideal for connecting pushbuttons, limit switches, proximity sensors, and photoelectric sensors.
Supports Sinking (NPN) and Sourcing (PNP) Wiring – Highly Flexible:Configurable via common terminal or jumper to accept both NPN (sinking) and PNP (sourcing) sensor outputs, ensuring compatibility with global sensor standards.
Galvanic Isolation for Strong Noise Immunity:Electrically isolated between field inputs and internal logic, protecting the CPU from surges and electrical noise for stable operation.
LED Indicators for Real-Time Signal Monitoring:Each input has a green LED to show active status, enabling fast visual diagnostics, commissioning, and troubleshooting on site.
Plug-and-Play Installation & Easy Mounting:Connects directly to the CPU via integrated bus connector; DIN-rail mounting saves space and simplifies panel layout.
Seamless Integration with S7-200 SMART System:Automatically recognized in STEP 7-Micro/WIN SMART software, no additional configuration required – inputs are immediately available in I-address space.
