Product Description:
The E4809-045-236-A RS Board from Okuma is also known to be referred to as A911-2913. This RS board is designed and manufactured in Japan by Okuma for industrial automation and to make serial communications between CNC controllers and external devices possible. It has several DB9 serial ports and a larger DB25 port for flexible connections.
The E4809-045-236-A board is perfect for data exchange in high-performance machine control procedures. The unit is powered by a regulated 5V DC supply for stable electronic functions. It has high-speed data processing ICs and serial communication drivers. The board incorporates NEC Japan communication chips for a reliable data flow. It accommodates both RS232 and the more complex RS-422 data transmission standards necessary for a versatile machine interface. Signal integrity is preserved, with differential signal support on its serial channels. Environmental tolerance covers operation between 0°C and 50°C ambient temperature. It is resistant to moisture changes of 90% relative humidity, non-condensing conditions. The E4809-045-236-A board is designed to run at vibration levels of 0.5G over the range of 10 to 55 Hz. The good construction permits stable operation up to 2000 m above sea level. Storage temperature is supported between -20 °C and 60°C to protect internal components.
The gold-plated connectors of the E4809-045-236-A board are resistant to corrosion and give a long life of electric contact. The board is conformally coated for dust and minor contaminants. Two large edge connectors connect to the system backplane. Low electromagnetic interference in industrial setups is achieved through the printed circuit board design. High-density component layout optimizes performance in confined cabinet space. This board is designed to conform to Okuma’s industrial expectations of machine reliability. It can be operated continuously are for a 24-hour manufacturing environment.
