Allen Bradley 1788-ENBT Ethernet I/P Communication Module

Description

The Allen-Bradley 1788-ENBT is an Ethernet I/P communication module. This electronic card is specifically called an Ethernet I/P daughtercard that fits directly into an assigned slot of a FlexLogix controller. The 1788-ENBT features one (1) RJ45 physical port that supports interfacing with Ethernet I/P networks at transmission speeds of 10 Mbps / 100 Mbps in half or full-duplex modes.

The 1788-ENBT has a small form factor. It is powered through the backplane and requires 5V DC @ 465mA, with a power consumption of 5V DC, 2.33W, and thermal dissipation of 8.0 BTU/hr. It has an isolated voltage rating of 500V AC for 60 seconds.

The 1788-ENBT supports direct connection or interfacing via standard Ethernet switches. It has simple cable requirements; thus, no cable scheduling and routing is needed. This communication port supports communication with Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA), converters, and gateways. It may also be utilized for sending and receiving messages to and from controllers in the network.

The 1788-ENBT is equipped with status LED indicators that indicate the network status, link status, and utilization percent.

Note: The 1788-ENBT does not support removal and installation under power (RIUP). When installing this module, ensure that the FlexLogix controller is without power.

The daughtercard has four (4) status LEDs: link status LED, module status LED, network status LED, and utilization percent LED. The 1788-ENBT has one (1) RJ45 port used for Ethernet interface. Before installing the daughtercard, ensure that the power is disconnected to avoid electrical arcs.
