The 1757-FFLD2 is designed to facilitate robust industrial communication and control. It operates on an input voltage range of 18 to 36 VDC, with a nominal input of 24 VDC. This device consumes a maximum of 36 watts of power while handling an input current of up to 1.5 amperes.Equipped with dual Ethernet ports, it operates at speeds of 10/100 Mbps and supports crucial protocols like EtherNet/IP and High-Speed Ethernet (HSE). Provisions for fieldbus connectivity are managed through two H1 ports, allowing for a communication speed of 31.25 kbps.
Dual H1 Ports
18...32V DC Input
0...60 °C Operating
The module ensures a high level of isolation with an Ethernet to H1 isolation voltage rated at 500 V RMS. It is built to withstand surges with a tolerance of ±2 kV across the H1 ports, contributing to its overall reliability in industrial settings.Furthermore, it demonstrates solid immunity against electrostatic discharge (ESD), rated at 8 kV for air discharge and 6 kV for direct contact discharge. The enclosure is rated IP20, making it suitable for environments where dust and solid objects are minimal.

Oil & Gas
The linking device connects EtherNet/IP networks to field devices in hazardous locations. It facilitates real-time data exchange for wellhead monitoring and custody transfer meters in upstream and midstream operations.
Chemical Processing
Enables integration of temperature and pressure transmitters across dual H1 segments with an operating range of 0…60 °C. It supports distributed control of reactors and storage tanks through seamless bridge communication.
Power Generation
Provides 18…32V dc power flexibility for monitoring cooling systems and steam turbines. The device ensures high-speed data throughput for diagnostic information in both fossil fuel and renewable energy facilities.
Water Treatment
Managed within an open-style enclosure for pump station control and wastewater filtration systems. It utilizes 31.25 Kbps Foundation Fieldbus H1 ports to maintain connectivity with remote flow meters and valves.
Pharmaceutical Manufacturing
Supports 5…95% noncondensing relative humidity for cleanroom process automation and batch control. The hardware facilitates precise instrumentation integration to meet stringent regulatory tracking and data logging requirements.
Mining & Metals
Designed to withstand 2 g operational vibration at 10…500 Hz for heavy-duty ore processing and smelting operations. It links Ethernet-based plant architectures to specialized Fieldbus sensors in high-interference environments.
The 1757-FFLD2 is designed for installation as an open-style device, necessitating its placement within a protective enclosure that meets specific environmental ratings to shield it from debris and ensure safety. To maintain operational integrity, the module requires a dedicated connection to a clean earth ground via the grounding screw, typically utilizing a 14 AWG copper wire to mitigate electromagnetic interference and ensure proper electrostatic discharge (ESD) immunity.
The current consumption of 500 mA at 24V dc, and it is essential that the power supply source remains within the 18...32V dc range to prevent thermal stress or hardware instability. During the configuration of Foundation Fieldbus H1 segments, attention must be paid to the total cable length and the correct placement of two terminators per segment, as the linking device provides the dual H1 communication ports but does not supply the internal bus power.
