Information About 1756-ENBT
The 1756-ENBT is part of the Allen-Bradley ControlLogix family, designed to provide seamless Ethernet connectivity for automation systems. It supports 10/100 Mbps communication rates in half or full duplex mode through a single RJ45 port and includes a USB 1.1 port for configuration. This module can handle up to 64 TCP and 128 CIP connections, allowing efficient data exchange between controllers, I/O modules, and other devices on an EtherNet/IP network. With a current draw of 700 mA at 5.1 VDC and 3 mA at 24 VDC, it operates with a maximum power dissipation of 3.7 W. The 1756-ENBT is also web-enabled, providing diagnostic tools and configuration access via a standard web browser, making it easier to manage networked devices.
Key Features:
- Communication Protocol: Supports EtherNet/IP with auto-negotiation at 10/100 Mbps for flexible operation.
- Port Options: One (1) RJ45 port for Ethernet connection and one (1) USB 1.1 port for configuration.
- Connection Capacity: Handles up to 64 TCP and 128 CIP connections for high-volume data transfer.
- Web-Enabled: Provides browser-based access for configuration, diagnostics, and monitoring.
- Power Requirements: Consumes 700 mA at 5.1 VDC and 3 mA at 24 VDC, with 3.7 W maximum power dissipation.
- Diagnostics: Offers monitoring of IP traffic, TCP/UDP activity, collisions, and connection management.
- Compatibility: Works with ControlLogix chassis in any slot and is backward compatible.
- Operating Conditions: Functions in environments from 0 to 60 °C (32 to 140 °F) with open enclosure mounting.
The 1756-ENBT delivers the reliability and precision required for Ethernet-based communication in ControlLogix automation systems.
