 ABB 83SR50C-E Control Module GJR2395500R1210 The ABB 83SR50C-E GJR2395500R1210 control board is a key component of the ABB Procontrol P14 system, designed for automation and control applications in a variety of industrial environments. The control module provides basic functions for process management and system integration. Product Features: -Due to the obsolescence of the Flash PROM (manufacturer: AMD) on the three modules 81EU50R1210, 83SR50R1210 and 83SR51R1210, a replacement component (manufacturer: Macronix) was implemented in October 2018. -In a project using modules delivered with new Flash, problems were found with writing/reading applications using PDDS. -The modules load applications via PDDS. These are first written to RAM. Subsequently, the module's handler copies the application from RAM to Flash. However, with PDDS, the process is complete after a successful write to RAM, so PDDS does not report any errors. -Copying from RAM to Flash does not happen or only happens partially. If you try to read back the application using PDDS, it is queried from Flash. Since there is no data or the data is incorrect, the error message "Disabled, list code not found" appears. -When unplugging and plugging the module, the application stored in RAM is deleted, because the memory is volatile. -Can be seamlessly integrated with other ABB devices and systems, making it convenient for users to build a complete industrial automation control system-In terms of anti-interference design, the ABB 83SR50C-E module has taken a variety of effective measures. First, suppressing interference sources is the top priority and the most important principle in anti-interference design. Reducing the du/dt of interference sources is mainly achieved by connecting capacitors in parallel at both ends of the interference source. -The power supply end should be as thick and short as possible, otherwise it will affect the filtering effect; avoid 90-degree folds when wiring to reduce high-frequency noise; connect RC suppression circuits at both ends of the thyristor to reduce the noise generated by the thyristor. Secondly, cutting off or attenuating the propagation path of electromagnetic interference is also an important anti-interference measure. For example, partition the PCB board to separate the high-bandwidth noise circuit from the low-frequency circuit; minimize the area of ​​the ground loop, etc. -In addition, improving the anti-interference ability of the device and system is also the key. Choose products with higher anti-interference ability, such as PLC systems with floating ground technology and good isolation performance.
