Description
The Allen-Bradley 1756-EN2F is a ControlLogix communication module, named by Rockwell Automation as CLX ENet/IP 100M Fiber. Rockwell's product data describes it as an EtherNet/IP module with 10/100M LC2 multi-mode fiber and 128 TCP connections. Rockwell lists a current draw of 1.2A at 5.1V DC and 3mA at 24V DC, power dissipation of 6.2 W, and an operating temperature of 0 to 60 °C. Rockwell shows its lifecycle status as Active.
Application: Communication module
Used with: ControlLogix 1756 chassis
What is the 1756-EN2F used for?
The module connects a ControlLogix chassis to an EtherNet/IP network through a single multimode fiber link with an LC connector. Rockwell lists its application as EtherNet/IP, and it can be fitted in any slot of the chassis.
Key features
- One multimode fiber LC Ethernet port
- 10/100 Mbps communication rate
- Supports EtherNet/IP and TCP/IP protocols
- Up to 128 TCP and 256 CIP connections
- Chassis based, any slot, one slot wide
