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

The ECU100-1T1F is an industrial slide-in Fast Ethernet card designed for modular media converter chassis and RACK-mounted platforms. It integrates 1× Fast Ethernet RJ45 port (10/100Base-T(X)) and 1× fiber port (100Base-FX, 1×9), offering reliable and EMI-resistant communication for industrial automation, SCADA and long-distance data transmission.

The card uses a store-and-forward switching architecture with an ultra-low latency of <10 μs, ensuring deterministic performance under real-time workloads. It is fully compliant with IEEE 802.3 / 802.3u / 802.3x, ensuring seamless integration with existing Fast Ethernet networks.

The RJ45 port supports auto-negotiation, auto-MDI/MDI-X, and both full- and half-duplex operation. The 100Base-FX optical interface enables stable long-distance communication and complete immunity to electromagnetic interference, making the module suitable for demanding industrial, energy, transport and smart-city environments.

Switching performance is powered by a 2K MAC address table, 448 KB packet buffer and 2.8 Gbps backplane bandwidth, which are characteristic of Fast Ethernet models within the ECU100 series :contentReference[oaicite:1]{index=1}. These parameters ensure low packet-loss and stable data flow even under heavy traffic conditions.

Designed for harsh field operation, ECU100-1T1F supports an extended temperature range of -40…75°C, up to 95% RH (non-condensing), and offers robust EMC immunity compliant with IEC 61000-4-2 / 4-4 / 4-5 (ESD, EFT, surge).

The module operates from a 5 VDC supply and features low power consumption: ≤1.5 W idle and ≤2.0 W at full load. Its compact dimensions (84.5 × 20 × 122.5 mm) and weight (≤80 g) allow for quick installation in modular converter platforms and RACK systems.
