ABB 933-7300 Power Module

ABB 933-7300 Power Module

It is a power supply module widely used in the field of industrial automation, specifically the external power supply unit of the S800 I/O series.

Key Features & Functions

1. Power Conversion:

   • Input: Typically 100-240V AC (wide-range input, adaptable to different power grids worldwide).

   • Output: Provides a stable 24V DC power source for the entire S800 I/O station.

2. Electrical Isolation:

   • Provides a high degree of electrical isolation between the input (mains power) and output (I/O power). This is crucial because it:

     • Prevents interference and surges from the main power grid from damaging sensitive I/O modules.

     • Improves the system’s noise immunity and overall stability.

     • Ensures the safety of personnel and equipment.

3. Compact Modular Design:

   • Uses the same mechanical design as the S800 I/O modules, allowing for easy installation on standard S800 mounting rails alongside other I/O modules, saving space inside the control cabinet.

4. High Reliability:

   • Designed for demanding industrial environments, featuring a robust housing and good thermal performance to ensure high reliability during continuous operation.

5. Plug-and-Play:

   • As a standard component of the S800 system, its installation and wiring are straightforward, enabling quick integration into both new and existing S800 I/O stations.

Primary Applications

The ABB 933-7300 power supply module is a fundamental building block for ABB automation systems (especially its renowned Advant / Freelance / System 800xA control systems). It is widely used in:

• Process Industries: Chemical, Oil & Gas, Pharmaceuticals, Pulp & Paper.

• Manufacturing: Automotive, Food & Beverage, Metal Fabrication.

• Energy & Infrastructure: Water Treatment, Power Plants.

In any application using ABB S800 Remote I/O, a power supply module like the 933-7300 is required to power the I/O station.

Role in the System

It can be thought of as the “heart” or “dedicated adapter” of an S800 I/O station:

• Mains power (e.g., 220V AC) is connected to the 933-7300.

• The 933-7300 converts this into a clean, stable 24V DC.

• This 24V DC power is distributed via the backplane to all other I/O modules in that station (e.g., digital input/output, analog input/output, communication modules).

• Finally, these I/O modules use this power to operate field devices such as sensors and actuators (e.g., valves, motor starters).
