Description

1. Function and Positioning
Power distribution module
It is mainly used to provide a stable DC power supply for other modules in the Mark VIe system (such as the processor module, I/O module, etc.), and supports redundant configuration to ensure the reliability of the system power supply.
Voltage conversion and monitoring
It converts the input power supply (usually external power supply) into the voltage required by each module (such as 5V, 12V, 24V, etc.), and monitors the power supply status in real time. It has overvoltage and undervoltage protection functions.
System redundancy support:
It can be paired with another power module for use to achieve power redundancy and avoid system downtime caused by a single point of failure.

2. Hardware characteristics
Input power supply:
Supports direct current (DC) or alternating current (AC) input, depending on the model configuration (please refer to the official manual for confirmation).
Input voltage range: Usually 100-240V AC or 24V DC (industrial-grade wide voltage design).
Output power supply:
Multi-channel DC output, powering different modules (such as 5V DC for logic circuits and 24V DC for I/O signals).
Output power: According to the module design, the output power of a single module can reach several hundred watts.
Interface and indicator light:
Power input interface: Used for connecting to external power supply lines.
Power output interface: Connected to other modules of the system via the backplane or cable.
Status indicator light:
Power OK: Green LED, indicating that the input power supply and the module are working properly.
Fault: Red LED, indicating overvoltage, undervoltage or internal fault.
Redundancy Status: Indicates the working status of the primary and backup power modules.
Mechanical Design
It conforms to the standard rack installation dimensions of the Mark VIe system and supports rail or backplane installation.
Compact structure, suitable for high-density deployment in industrial environments.
