Product Description:

The Okuma produces E0241-653-101 MSM Board, which functions as an industrial automation circuit board intended for CNC systems. Under dry conditions, the insulation resistance tests are performed at more than 100 MΩ at 500 VDC. Insulation testing occurs at 1.5 kV AC voltage for a minute duration. The ideal range of relative humidity for operations exists between 20% to 85% non-condensing.

Control logic functions delivered by this E0241-653-101 MSM board ensure dependable CNC operations. The board incorporates serial communication functionality through various 8251AFC and 8253C-5 chip devices integrated with its timing control systems. Secure signal transmissions are enabled through the DB-type ports located on the connectors. The dimensions of the PCB measure about 330mm by 280mm according to visual assessment. Stable placement occurs when using the gold-plated edge connector. The E0241-653-101 MSM board power systems require a standard 5V DC logic power supply. Flooded operation consumes an electrical current that does not exceed 1.5A. This control system accepts TTL output signals from the supported incremental encoders. The encoder signals come out with a resolution of at least 1024 PPR, along with higher resolution options. The component enables operation at 0.5 G within the 10-55 Hz frequency range. The equipment should not be installed in zones where shock incidents persist or grow amplified.

This E0241-653-101 MSM board has an operating temperature range from 0°C to 50°C. The storage range for this equipment exists between -20°C and 75°C. The board can be installed at elevations below 1000 meters above sea level. Derating of components requires implementation beyond certain operational conditions. Through serial interfaces, the communication speed can reach 9600 bps. The board contains an array of integrated circuits that range from logic chips consisting of SN74LS and SN7416N family components.
