2C15 Electrical Interface Module

Weed Instrument A-B DH-485 Electrical Interface Module.

The 2C15 Module provides electrical interface for Allen-Bradley DH-485 networks by conditioning the electrical signals supplied to and from the DH-485 equipment for transmission over the fiber optic network.

The simplest modem configuration consists of a Power Supply, an Electrical Interface, and an Optical Interface Module. However, additional modules may be added to configure Daisy Chain, Star, Self-Healing Ring topologies and provide Redundancy. A maximum combination of five optical or electrical modules may be connected together in one modem, inter-module communications and operating power is achieved through the integrated module interconnections.
