Product Name: Power Distribution Board
Manufacturer: Tokyo Electron Ltd. (TEL)
Installation method: rack plug-in/backboard hanging type
System: Control host rack/I/O sub rack/power cabinet
2、 Core functions
Multi channel power access and conversion
Input DC power (such as+24V,+12V,+5V, ± 15V DC) from the main power module (such as 3D80-001480-V1);
Filter, stabilize, and protect the input voltage.
Power distribution and output
Output the stabilized power supplies to various functional modules (such as controllers, I/O boards, communication modules, and actuators) through branch circuits;
It usually supports multiple independent power supply circuits and can be connected to aviation plugs, backplane pins, bolted terminals, etc.
Protection and monitoring functions
Each output is equipped with safety circuits such as fuses, current limits, reverse polarity protection, and short-circuit protection;
Support feedback of overcurrent and over temperature alarm signals to the main controller (such as E244 or BX81 system).
Voltage indication and status feedback
Onboard voltage status indicator light, convenient for operation and maintenance personnel to judge the working status;
Some models support connecting digital monitoring boards for remote power status acquisition and alarm processing.
