Product Description:

The model E4809-032-219-J is designed as a circuit board that processes and controls digital signals between the main unit and peripheral components. The manufacturing entity Bosch creates this part and uses rugged designs for steady operation in multiple industrial automation sectors.

The E4809-032-219-J circuit board belongs to the signal handling and processing part of CNC machine controllers. It mainly uses TTL logic and relies on SN74 series integrated circuits that provide basic gates, flip-flops and inverters. Several gates are structured to control the changes in logic states and save data for the control system. TTL integrated type circuits are designed for use with varying voltage levels as 4.75 V to 5.25 V and have standard DIP packing that can be easily changed for testing or removal purposes. A capacitor is placed close to the IC’s power pins for the purpose of decoupling which helps stabilize electricity and reduce sudden disturbances. Traces on the board are well-defined and the parallel bus structure is then directed to the gold-finger edge connector. By using industry spacing and separation methods for the layout many signal interference issues are avoided.

The E4809-032-219-J circuit board uses Pull-up resistors and diodes which help the logic sections and guarantee well-behaved digital signals. All component positions are shown by silkscreen such as H04 and E1 so they can be referred to during maintenance and repairs. The board is combined using the through-hole technique. It has a fiberglass-reinforced bottom covered with epoxy for extra support and solidity. Using the file board makes it possible for programs and machines to perform in an orderly manner on the CNC machine.
