E4809-436-108-A
by Okuma
The Okuma E4809-436-108-A board is part of the E4809 CNC Boards series, engineered by Okuma for precise industrial automation control. Featuring an Input Voltage range of 100–240 VAC and a regulated Output Voltage of 24 VDC at 8.3 A, this chassis-mounted circuit board ensures reliable power distribution. With dimensions of 295 x 127 x 60 mm, it is designed for seamless integration into machine control cabinets, providing modular signal management for spindle, jog, and feed systems through clearly marked connectors.
Beyond power delivery, the E4809-436-108-A excels in signal integrity and mechanical robustness. It employs a 5 V DC regulated supply for internal logic and supports low-voltage differential signaling to minimize electrical noise. The board’s system integration is facilitated by a high-density XB12 connector interface and gold-plated pin contacts, guaranteeing long-term stability and ease of troubleshooting. Signal ports labeled XB-CPH, XB-EXSW, and XB-FEED interface directly with optical and mechanical encoders via TTL signals, enabling accurate servo motor feedback. Protection features for Over Voltage, Over Current, and Over Temperature safeguard the board under heavy loads and transient events.
Designed for durability and compatibility, this unit operates reliably within an ambient temperature range of 0°C to 45°C (up to +50°C maximum) and can be stored between -20°C and 60°C without degradation. It tolerates relative humidity up to 85% (non-condensing) and mechanical vibrations up to 0.5G at 10–55 Hz. Rated for operation at elevations up to 2000 meters, the board’s lightweight 1.5 kg chassis mount design offers convenient installation across diverse environments. By delivering stable signal processing, robust protection, and simplified maintenance, the E4809-436-108-A optimizes machine tool performance and maximizes uptime in demanding industrial settings.
