Product Description:
The E4809-045-039-G circuit board finds its uses in motion control systems to manage the movement of servo motors along specific axes. It is made by Okuma , the firm excels through the remarkable design of industrial automation parts.
The E4809-045-039-G circuit board is mainly employed in axis control systems. It weighs about 0.62 kilograms only and features a multi-layer PCB with logic, memory and signal interface functions. It has a variety of TTL logic ICs from the HD74LS series by including HD74LS04P inverters, HD74LS74AP flip-flops and HD74LS157P multiplexers. These components manage digital logic operations, signal transition and timing control without complex external circuitry. For temporary data access and handling, it contains TMS4727NL static RAM chips which function at standard TTL voltage levels and provide fast access times suitable for real-time axis operations. It works with four ceramic DIP modules labeled JD6190B J420 configured as control ROMs or custom microcontrollers. These operate with critical routines for interpretation and drive output conditioning. The module uses multiple blue D-sub connectors (DB25 or DB37) located on the right edge which handle I/O communication to servo drives and encoder feedback lines.
The E4809-045-039-G circuit board contains power and bus interfacing which are handled via a gold-finger edge connector positioned along the left side which links it into the host OPUS5000 system. Filtering and EMI suppression are achieved using discrete capacitors by ranging from 0.1 micro-farads to 2200 pico-farads near the power entry points. Signal integrity is further maintained through a custom module marked as TDK CP-4606 which is used for noise filtering or transient protection. A central processor unit housed in a purple ceramic DIP package acts as the processing core for motion routines.
