The 1757-FFLD2 ControlLogix module by Allen Bradley 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.

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.
