Honeywell 10303/1/1

Usage parameters

General: The general model of Honeywell 10303/1/1 is 10303/1/1 03501*, which is certified by CE, TÜV and UL, and is compatible with all software versions.

Space requirements: With compact size, it requires 4 TE (4 HP) and 3 HE (3 U) of space and can be installed in various control cabinets or equipment racks.

Electrical parameters: As a passive module, it does not require an external power supply. In extreme cases, for modules without suffix codes, its maximum current is limited to 20 A (module power dissipation). At the same time, the maximum reverse voltage limit is set to 30 V and the forward voltage drop is limited to 0.55 V.

Terminal parameters: The terminal type is DIN 41612 - H15P (Faston), and the maximum current through the connector is limited to 10 A per pin.

Function

Power Distribution and Conversion: The main purpose of the 10303/1/1 module is as a Power Distribution Module (PSD). In systems where redundant central units and non-redundant I/O coexist, it takes 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 associated with the system. This guarantees a stable and repeated power supply to the I/O components, which is essential for the proper operation of the system.

Voltage Drop Control: The power supply should always flow into the central section of the system through this module to ensure equal voltage over the entire length from the power supply to the I/O section. This ensures that the power supply is evenly loaded along its length and prevents any voltage fluctuations that could degrade system performance and reliability. In addition, the 5 VDC power supply range is quite strict within the allowed range (±5%), so the PSD module must be installed close to the PSU module to minimize voltage drops in the wiring. The minimum recommended wire size is 2.5 mm² (AWG 14).

Safety and Maintenance: The PSD module can only be replaced in the de-energized position of its associated PSU. This is a safety feature that avoids electrical hazards during system replacement and preservation.

Application Scope

Chemical industry: In the chemical production process, it is used to ensure a stable power supply for various control devices and sensors (such as temperature sensors, pressure transmitters and flow meters). This helps to maintain the accuracy and reliability of process control, thereby ensuring the quality and safety of chemical production.

Petroleum industry: Provide reliable power distribution for key equipment and control systems such as oil storage tanks, pipelines, and refining processes in refineries and petrochemical plants. Stable power supply helps prevent equipment failures and production interruptions, thereby ensuring the normal operation of the entire oil production process.

Building materials industry: In the production process of building materials such as cement plants and glass plants, it powers control systems and sensors, monitors and manages production parameters such as temperature, pressure, and material flow, and ensures the quality and consistency of building materials production.

Aerospace industry: In aerospace manufacturing and testing facilities, it provides stable power for various precision instruments and control systems, and provides accuracy and reliability for the testing and production processes of aerospace products.

Electrical industry: It can be used in electrical facilities such as power plants and substations to provide power distribution for control systems and monitoring equipment to ensure stable operation of the power grid and power supply safety.
