1788-EN2FFR

The Allen Bradley 1788-EN2FFR functions as a converter for EtherNet/IP to FOUNDATION Fieldbus applications, facilitating seamless communication between these protocols. It operates with Category 5 STP/UTP cabling and is built to endure a shock of 30 g. The device incorporates two isolated channels for FOUNDATION Fieldbus H1, delivering a data transfer rate of 31.25 kbps.

With a wide power supply output ranging from 9 to 32 V DC, the 1788-EN2FFR ensures compatibility with various systems. Power consumption is rated at 260 mA at 24V, measured without any field devices connected. This linking device’s robust construction includes terminal torque specifications of 0.22 to 0.25 N•m for DC power connections and 0.21 to 0.25 N•m for FOUNDATION Fieldbus connections.

Protection against electromagnetic interference is essential for proper functioning; thus, this device offers EFT/B immunity of ±4 kV on power ports and ±3 kV on communication ports. It also features surge transient immunity rated at ±2 kV line-to-earth on the communication ports to enhance reliability. Conducted RF immunity is rated for 10V rms from 150 kHz to 80 MHz, which is critical for maintaining signal integrity in noisy environments.

The device additionally displays impressive ESD immunity with contact discharges up to 6 kV and air discharges reaching 8 kV, allowing it to operate safely in environments prone to static discharge. With a power dissipation rating of 12.24 W at 24V DC, this linking device is effective in managing thermal conditions during operation.
