ECU100-2T1F – Industrial Fast Ethernet Slide-In Card with 2×RJ45 and 1×Fiber 100Base-FX

The ECU100-2T1F is an industrial slide-in Fast Ethernet card designed for modular media converter chassis and RACK platforms. It features 2× Fast Ethernet RJ45 ports (10/100Base-T(X)) and 1× fiber port (100Base-FX, 1×9), providing reliable and noise-immune long-distance communication for industrial and automation networks.

The device uses a store-and-forward architecture with ultra-low forwarding latency of <10 μs, ensuring deterministic transmission for SCADA, PLC communication, telemetry systems and real-time industrial applications. It complies fully with IEEE 802.3 / 802.3u / 802.3x, ensuring compatibility with modern Fast Ethernet infrastructures.

The dual RJ45 ports support auto-negotiation, auto-MDI/MDI-X and full/half-duplex modes. The 100Base-FX fiber port provides stable long-distance communication, fully immune to EMI, making the module a strong fit for power utilities, transportation, smart-city networks and industrial automation.

High switching performance is achieved through a 2K MAC address table, 448 KB packet buffer and a 2.8 Gbps backplane bandwidth, typical for Fast Ethernet models within the ECU100 series :contentReference[oaicite:1]{index=1}. These parameters ensure minimal packet loss and stable throughput even under heavy traffic, such as industrial monitoring or control systems.

Designed for harsh industrial environments, ECU100-2T1F offers an extended operating temperature range of -40…75°C, humidity tolerance up to 95% RH (non-condensing), and complete EMC immunity meeting IEC 61000-4-2 / 4-4 / 4-5 requirements, including ESD, EFT and surge protection.

The device operates from a 5 VDC supply with very low power consumption (≤1.5 W idle, ≤2.0 W under full load). Its compact dimensions (84.5 × 20 × 122.5 mm) and weight (≤80 g) make installation fast and efficient in modular converter platforms.
