E4809-045-106F by Okuma

The E4809-045-106F from Okuma operates at 5V DC TTL logic and features a gold-plated edge connector. Part of the E4809 CNC Boards, it works with the OPUS 5000 II control system and mounts via L type side brackets. The board includes custom OKUMA ICs OCL512 GRC and OCL513 LUT plus blue multi-pin I/O connectors.

It uses a standard green solder mask and fits a standard 19 inch rack for robust protection. A crystal oscillator provides accurate clock timing. The design achieves 90% efficiency.
