8-Channel Digital I/O Integrated Module:Combines 4 digital inputs (DI) and 4 digital outputs (DO) in one compact unit, enabling both signal acquisition and control output in limited space.
Compact Design Saves Rack Space:Occupies only one slot on the S7-300 rack, ideal for small-scale expansions where space is limited and minimal I/O points are needed.
24V DC Signal Level Compatibility:Supports standard 24V DC industrial signals, directly connectable to sensors (e.g., pushbuttons, limit switches) and actuators (e.g., relays, indicator lamps).
Non-Isolated Design for Cost Efficiency:No electrical isolation between channels, optimized for cost-sensitive applications without high insulation requirements.
LED Status Indicators for Easy Diagnostics:Each channel has an LED to show real-time status, enabling fast visual troubleshooting and commissioning on site.
Plug-and-Play Installation:Uses standard front connectors (e.g., 6ES7392-1BJ00-0AA0), allowing quick wiring, installation, and replacement, minimizing downtime.
