Product Description:

Okuma E4809-907-022 Network Board is a high-performance interface module made for precise connection and control in automated systems. The board is designed to work with several different signal types and is easy to connect to control systems used in industrial automation.

The E4809-907-022 network board has two green interface blocks with the labels XB-DN1 and XB-DN2 that are meant to communicate over DeviceNet. Plastic headers with the numbers XB-1 to XB-4 and XB-Y are extra connectors that can handle sensor or encoder feedback. A big black port on the board, labeled XB-NCOK, handles connecting to a multichannel data or power bus. Connectors XB-5 to XB-8 on the right side allow for more I/O connections or servo signal interfacing. Altera's EPF6016AQC208-3 and EPF6016AQC208-2 FLEX FPGAs can process data quickly and control logic that can be programmed. The SJA1000 CAN driver can talk over the CAN bus, which is used in DeviceNet protocols. RS-232 serial transmission is made possible by the ADM202 IC. There are voltage controllers and a number of capacitors built in to filter signals and keep the power stable. These parts make sure that the process always works correctly and that the signals stay intact.

The E4809-907-022 network board also has a crystal oscillator that keeps the clock time stable so that the FPGA can work. On the board is a DIP switch block that lets you set up specific hardware addresses or communication modes by hand. Its small size and well-organized layout of connectors make it possible for different hardware layers to communicate effectively. The board has important processing and transmission features that meet the needs of modern industrial automation systems.
