Product Description:
The E0227-702-010 circuit board serves as an accurate medium for long-term data protection by verifying that stored information is preserved even when the system is turned off. It is designed by Okuma and has created advanced technologies that boost energy and are better for vast industries.
The E0227-702-010 circuit board functions as a bubble memory card used within OPUS 5000 control systems. It carries four modules each with a capacity of 4 megabits by providing a total memory capacity of 16 megabits as 2 megabytes. The board is responsible for the long-term storage of system data, machining programs and user-defined parameters. It functions by storing data magnetically which aids in allowing retention even when power is removed which suits industrial automation applications where data preservation is essential. It is constructed with a protective metal shield that covers the memory section by removing electromagnetic interference. The weight of the unit is only 0.60 kilograms by making it compact for internal installation. The board features a row of EPROM ICs which aids in including standard types like the uPD2764 to store firmware and fixed routines necessary for the interface purpose.
The E0227-702-010 circuit board’s voltage regulation is handled with parts such as IC6 with a linear regulator by ensuring a stable +5V supply to sensitive sections. Connectivity is done through an edge connector (CN1) for backplane communication with the system. Several socketed positions from IC26 to IC29 are provided for serviceability. Discrete resistors, capacitors and signal conditioning elements are present throughout to keep electrical balance and clean data lines. The presence of a quartz crystal oscillator provides a fixed frequency clock essential for memory timing. The board also includes inductors for line filtering and improving signal clarity.
Frequently Asked Questions about E0227-702-010:
Q: Is the E0227-702-010 compatible with all Okuma controllers?
A: No, the E0227-702-010 is built specifically for the OPUS 5000 controller and may not function in other Okuma series without modification.
Q: How much memory capacity does the Okuma E0227-702-010 offer?
A: It provides a total of 16 megabits (2 megabytes), configured through four 4 Mbit bubble memory units.
Q: Does the E0227-702-010 require battery backup for data retention?
A: No, it uses non-volatile bubble memory technology, which retains data without any power or external backup source.
Q: What type of memory technology is used in E0227-702-010?
A: It uses magnetic bubble memory, a non-volatile memory type capable of long-term storage under harsh industrial conditions.
Q: How does the E0227-702-010 communicate with the main system?
A: The board uses an edge connector interface (CN1) to link with the backplane of the CNC control system.
