Product Description:
The Okuma E4809-770-099-B Circuit Board is a custom electronic module designed for industrial automation applications. It features a robust construction with support for multiple logic and communication tasks. This board is commonly used in industrial systems that require signal conditioning, peripheral interfacing and relay control.
This E4809-770-099-B circuit board features an L shaped printed circuit board (PCB) design. The unique shape allows flexible installation in custom enclosures and rack mounted systems. It includes six mounting holes for secure screw or standoff based mounting. Multiple connectors and headers are arranged across this board for efficient signal routing. These include a relay socket (XB1), rectangular headers (XB2 to XB7) and various DB style connectors (XB8, XB10). The XB11 connector is a long multi pin socket used for system bus interfacing. Additional headers like RC1 to RC5 and RA1 to RA2 provide internal or auxiliary connections. This board supports critical functions through integrated logic ICs such as the 74HC244, 74HC240 and 74F244 octal buffers. These components handle high speed signal transmission and drive capabilities. The 74ALS273 registers manage data latching and the 4049BF inverting buffer ensures clean signal transitions. This board supports multiple electrical functions such as input/output signal buffering, relay switching and system timing. It interfaces with external devices through several pin headers and bus lines.
The onboard crystal oscillator (KHC8700A) in this E4809-770-099-B circuit board provides a 40.0000 MHz clock source for timing sensitive functions. This precision clock supports the operation of various digital components. The Hitachi DPC00L4LB electromechanical relay mounted via socket XB1 is used for load switching and electrical isolation. Multiple electrolytic capacitors rated at 33 uF offer transient protection and voltage stabilization across the circuit.
