SD208

The SD208 is an integrated remote I/O controller designed for high-standard industrial data acquisition and control using the Modbus TCP protocol. It features a rugged, fanless aluminum alloy housing with an IP40 rating and a 35mm DIN-rail mount.

I/O Capacity: Features 8 PNP/NPN digital inputs (DI) and 8 digital outputs (DO).
Connectivity: Equipped with dual 10/100Mbps Ethernet ports supporting auto-negotiation and MDI/MDI-X.
Isolation & Protection: Offers 500 VAC optical isolation for all I/O channels, along with overvoltage, overcurrent, and overload protection for DO.
Industrial Durability: Operates reliably in harsh environments from -40 to +75C.
Power: Supports a wide DC 9–36V input with reverse polarity protection.
Modbus TCP Master Support: Handles up to 8 simultaneous master connections and supports various function codes (DI: 02/03/04; DO: 01/03/05/06/15/16).
Signal Stability: Integrates DI input filtering (0–20 ms) and input holding functions to ensure data accuracy.
