The IOC-555-D 17-550555-001 provides 16 serial input/output channels, supporting differential or single-ended signals (e.g., 8 differential/16 single-ended inputs), and can handle current/voltage signals (e.g., 0-5V DC, -5 to +5V DC). It integrates Ethernet (Gigabit/10/100BaseTX), serial ports (RS-232/485), USB, etc., supports Modbus TCP/IP, Profinet, and other protocols, and is compatible with OPC stations and DCS/SIS system linkage. It supports expansion chassis for long-distance (e.g., within 12 kilometers) I/O module connections, making it suitable for distributed control systems and widely used in critical process control in high-risk industries. Its powerful signal processing and diagnostic capabilities ensure stable system operation and rapid fault response in harsh environments.
