- **Dual Ethernet Ports with Daisy‑Chain Topology:** Integrated 10/100 Mbps Ethernet switch with auto‑bypass protection allows daisy‑chain networking. If a module loses power, the network automatically recovers within ~1 s, maintaining communication continuity. - **Industrial Modbus/TCP and UDP Support:** Fully compliant with Modbus/TCP over TCP/IP and UDP/IP for open interoperability with controllers, HMIs, and SCADA software. Supports up to eight UDP data stream destinations. - **Mixed I/O Architecture:** Combines digital inputs and outputs in one compact module, reducing system cost and simplifying distributed I/O deployment. - **Isolated I/O Channels:** 3750 Vrms optical isolation between channels and logic circuitry ensures robust protection against electrical noise and ground loops. - **DIO Synchronization (Mirror DI to Local/Remote DO):** Enables automatic mirroring of input states to local or remote outputs, supporting both “DI match DO latch” and “DI mismatch DO latch” modes. - **DO Auto‑Off Time Mode:** Configurable monostable output operation—after a preset time, the output automatically returns to its stable state. - **High/Low Delay Output Modes:** Programmable delay for transitions from low‑to‑high or high‑to‑low output states, useful for sequencing and timing control. - **Power‑On and Safe Values:** User‑defined output states at power‑up or upon host watchdog timeout, ensuring predictable and safe system behavior. - **Comprehensive Software Ecosystem:** Includes Windows configuration utility, Modbus/TCP OPC server, DLL and ActiveX libraries (TCPDAQ), and ASCII command interface for custom integration. - **Built‑in Web Server:** Embedded HTTP server for remote monitoring and control via standard web browsers.
