1. Product Overview
The IC693PWR321 is a power supply module within the GE Fanuc IC693 series of Programmable Logic Controller (PLC) systems. Power supply modules are fundamental components in PLC setups as they are responsible for converting incoming electrical power into stable and appropriate voltages to energize other modules in the PLC rack, such as input – output (I/O) modules, communication modules, and the central processing unit (CPU).
2. Product Parameters
| Parameter | Details |
|---|---|
| Input Voltage | It can accept a wide range of input voltages, typically 100 – 240V AC, 50/60Hz. This wide input voltage range makes it suitable for use in different regions around the world, accommodating various power grid standards without the need for additional voltage – conversion equipment. |
| Output Voltage | Provides a stable 24V DC output voltage. 24V DC is a common and standard voltage in industrial control systems, widely used to power a variety of PLC – related components. |
| Output Current | Has an output current capacity of around 5A. This current rating allows it to supply sufficient power to multiple modules in the PLC system, depending on their individual power requirements. |
| Power Efficiency | Generally has a high power efficiency, often greater than 90%. High efficiency means less power is wasted as heat during the conversion process, which not only reduces energy consumption but also helps in maintaining a lower operating temperature for the module and the surrounding components. |
| Over – current Protection | Equipped with over – current protection functionality. It will automatically shut down the output if the current exceeds a certain threshold (e.g., around 6A). This protects the power supply module and the connected PLC components from damage due to excessive current draw, such as in the case of a short – circuit in the load. |
| Over – voltage Protection | Protects against output voltages exceeding a safe level, typically around 28V DC. Over – voltage can cause damage to sensitive electronic components in the PLC system, so this protection feature is crucial for ensuring the longevity and reliability of the system. |
| Isolation | Offers electrical isolation between the input and output with an isolation voltage of around 1500V AC. This isolation helps prevent electrical interference from the input power source from reaching the output and the connected PLC modules, improving the overall stability of the system. |
| Operating Temperature Range | Can operate within a temperature range of – 20°C to 60°C. This wide temperature tolerance allows the module to be used in various industrial environments, from cold storage facilities to hot manufacturing plants. |
| Dimensions | Has compact dimensions, approximately 177mm (length) x 100mm (width) x 62mm (height). This compact size makes it easy to install in standard control cabinets, saving space in the control panel. |
| Weight | Weighs around 1 kg, which is relatively light and does not add significant weight to the overall PLC system. |
| Compatibility | Designed to be fully compatible with specific models in the GE Fanuc IC693 PLC series, ensuring seamless integration into existing or new control systems using this series. |
3. Advantages and Features
- Universal Input Compatibility: The ability to accept a wide range of input voltages (100 – 240V AC) makes the IC693PWR321 a versatile choice for global applications. It simplifies the procurement process as a single power supply can be used in different locations with varying power grid conditions.
- High – efficiency Power Conversion: With a power efficiency of over 90%, it reduces energy consumption and heat generation. Lower energy consumption leads to cost savings over time, and less heat helps in extending the lifespan of the module and other connected components by reducing thermal stress.
- Robust Protection Mechanisms: The over – current and over – voltage protection features provide reliable safeguards for the power supply and the connected PLC components. In case of a fault, the module can quickly shut down or limit the output to prevent damage, minimizing downtime and repair costs.
- Electrical Isolation: The 1500V AC isolation between the input and output helps in eliminating electrical noise and interference from the input power source. This results in a cleaner and more stable power supply for the PLC system, reducing the risk of system malfunctions.
- Compact Design: Its compact dimensions allow for easy installation in standard control cabinets, making it suitable for applications where space is limited.
4. Application Fields and Application Cases
