GE DS200CTBAG1A has CC and DD suffixes on the board. From the perspective of the product appearance, there are fixed hole positions reserved at the four corners, which are in accordance with the standard European slot installation of Mark V. The green terminal block is used to connect on-site RTD platinum resistors, thermocouples, transmitters and vibration sensors. The built-in chip-type current-limiting resistor is to prevent short circuits at the site and reverse injection of voltage. In the middle of the product, there are 2 NNC coaxial interfaces, vertical red surge protection, and RS32 interface connector.

Common Faults in Factory Use and Maintenance Tips

Terminal blocks often oxidize or get damp in chemical plants and coastal power plants;

During the annual thunderstorm season, lightning can break through MOV voltage-sensitive resistors, causing abnormal signals for a single path or the entire group;

Loss of the terminal resistor for COREBUS will result in complete board communication interruption and the main control going offline;

Also, basic faults such as aging capacitors bulging occur;

How to achieve correct installation and maintenance

1. When disassembling or assembling, wear an anti-static wrist strap (CMOS components have a high risk of static breakdown);
2. For idle COREBUS (JAI/JAJ), a 75Ω terminal resistor must be installed;
3. Spare parts should be stored in a constant-temperature anti-static cabinet and must not be stored outdoors.
