Product Description:
The E4809-770-053 Circuit Board is a rectangular PCB designed for power and signal processing applications. It features both through hole and surface mount components to optimize performance and reliability.
The Okuma E4809-770-053 circuit board is equipped with a large multi pin edge connector for seamless interfacing. It incorporates large heat dissipation pads and power traces to ensure thermal efficiency and stability. This circuit board is built to handle high speed switching and power management tasks. This circuit board includes several power components including eight power transistors (T1 - T8) which are either MOSFETs or IGBTs designed for efficient high speed load switching. Each transistor is protected by a dedicated diode (D1 - D8) to prevent voltage spikes. Resistor arrays are integrated in this board for signal stabilization including RA1 (47 KΩ x 8) for pull up or pull down applications, RA2 (10 KΩ x 8) for logic level stabilization and RA3, RA4 and RA5 (2 KΩ x 4 each) for current limiting purposes. This board also features capacitors that assist in power filtering and stabilization. The integrated circuit section includes an HCT273 Octal D-Type Latch IC which provides data latching for outputs and PC827 optocouplers which offer galvanic isolation between control logic and the power section. These optocouplers protect microcontrollers and logic circuits from potential high voltage damage.
The E4809-770-053 circuit board is equipped with an Omron A6DR-4 relay module which provides high reliability when handling higher power loads. This circuit board is designed with multiple connectors including a large edge connector (CNI) that facilitates interfacing with CNC systems. Additionally, smaller connectors (CN8 and others) are present which may serve as test points, additional control signal inputs or feedback mechanisms.
