Functional FeaturesVogi

Power Distribution And Conversion: The 10303/1/1 module functions principally as a Power Distribution Module (PSD). In those systems where redundant central units and non-redundant I/O coexist, it accepts the output from the redundant central section Power Supply Unit (PSU) and assembles it into a single 5 VDC power supply for the non-redundant I/O section that is linked with the system. It ensures that the I/O components are supplied with a steady and recurring power supply, a necessity for the functioning of the entire system.
ensures that voltage is current shared across the length of the system → current is drawn evenly from the input of the system over input voltage may drop in the I/O group in current heavy systems. This avoids any voltage fluctuations that would degrade system performance and reliability life, such that the power supply gets loaded uniformly throughout its length. Additionally, the 5 VDC power supply range is very tight inside the margin (±5%) therefore PSD module must be placed close to the PSU module to avoid voltage drop in the wire. The minimum cable size recommended is 2.5 mm² (AWG 14).
Safety and Maintenance: PSD module replacement is possible only in a PSU de-energized position. This is a safe process preventing electric risks in the replacing and storing systems.

Application AreasVogi

Honeywell 10303/1/1 - power distribution module is widely used in various industrial fields combining redundant and non-redundant power supply circuits. Typical applications include:
Chemical Industry: It is used to ensure the stable power supply of all kinds of control devices and sensors (temperature sensor, pressure transmitter and flowmeter, etc.) in the process of chemical production. This is important because it helps to ensure the quality and safety of chemical production.
Oil: Maintain secure power delivery for key machinery and control systems like oil storage tanks, pipelines, and refining operations in both refineries and petrochemical plants. The stable power supply can prevent equipment failure and production interruption, so that the normal operation of the entire oil production process.
The building materials industry: It is mainly used to power control systems and sensors in cement plants, glass plants and other building materials production processes, monitor and control temperature, pressure, flow and other production parameters, and ensure the quality and consistency of building materials production.
Aerospace Industry: Offering stable power for various precision instruments and control systems in aerospace products, it guides the accuracy and reliability of aerospace product testing and production process.
Electronics: Safety power supply module can be used in power system and substation and etc. electrical facilities, for control systems and monitoring equipment to provide power distribution, to ensure the stability of the power grid and safety of the electric power supply.
