Product Description:
The E4809-770-086-E Circuit Board is manufactured by Okuma and is designed to function in conjunction with CNC operator interface systems. The board is primarily responsible for coordinating the tasks of the CNC control systems and mechanical control components, including knobs, switches, and signs.
The E4809-770-086-E circuit board has several ribbon connectors, including 10-pin and 14-pin types that make it easy to connect to different control elements. The board has blue D-sub style headers that allow for safe and long-lasting cable hookups. HC245, HC244, and HC14 are integrated circuits on the board that work as buffers and inverters to handle logic-level signals. There are Omron G5V-1 style relays fixed that handle low-power switching for the outputs. In this package, there are electrolytic and ceramic capacitors that filter and separate the data and power lines. There are silkscreen marks on the PCB that say things like XB3, XB5, XB11, and XB12, which help with finding cables and routing them correctly. The board is mounted with four screw holes, which allows for both mechanical attachment and electrical grounding inside the control box. The board is meant to connect to CNC control series like the OSP500, OSP700, OSP1000, OSP2000, or E5 Panels, which are used in factory automation systems.
The E4809-770-086-E circuit board also lets the emergency stop circuits and the CNC processor talk to each other, which keeps the operator safe. It takes data from the machine's front panel selector switches and status lights and processes them. The board has solder mask clearances that meet consistent production standards and trace-width sizes that meet controlled impedance requirements. The design considers the fact that certain discrete logic control circuits are employed in legacy or hybrid CNC configurations.
Frequently Asked Questions about E4809-770-086-E:
Q: Why does E4809-770-086-E use HC245 ICs?
A: HC245 ICs provide bidirectional buffering. They ensure controlled signal direction between the CNC control logic and the front panel devices.
Q: Does E4809-770-086-E have D-sub headers?
A: Yes, it features blue D-sub-style headers. These enable reliable multi-pin connections for consistent electrical contact.
Q: Do E4809-770-086-E relays handle switching loads?
A: E4809-770-086-E uses Omron G5V-1 style relays. These are suitable for low-power output switching in CNC panel circuits.
Q: Why does E4809-770-086-E have labeled silkscreen?
A: Labeled silkscreen areas like XB3 and XB5 assist installation. They help identify cable routes and reduce connection errors.
Q: How do E4809-770-086-E capacitors improve function?
A: Electrolytic and ceramic capacitors are used for filtering. They reduce electrical noise and stabilize voltage levels on the board.
