ABB PM866AK02
Product Description
The ABB PM866AK02 is a redundant processor unit designed for the AC 800M controller series1. It features a redundant CPU architecture with dual CPUs, ensuring high availability and fault tolerance6. This is achieved through a robust CEX – Bus communication system6. It also offers communication redundancy with dual communication ports and supports redundancy for S800 I/O modules6. The module is built to withstand harsh industrial environments and is suitable for applications requiring continuous operation, such as power plants and industrial automation systems6.
Product Parameters
- Power Supply: Usually operates on an industrial – standard power voltage, such as 24 VDC1.
- Communication Ports: It has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network and two RJ45 serial ports (COM3, COM4). One serial port (COM3) is an RS – 232C port with modem control signals, and the other port (COM4) is isolated for connecting configuration tools1.
- Memory: Equipped with a certain amount of application memory to handle various control tasks. The specific capacity may vary depending on the model and configuration.
- Processor Speed: Operates at a speed suitable for processing control data in industrial automation systems. The exact speed is related to the specific microprocessor used.
Product Specifications6
- Dimensions: Width: 119 mm (4.7 in), Height: 186 mm (7.3 in), Depth: 135 mm (5.3 in).
- Weight: 2.7 kg (6.0 lb).
- Operating Temperature Range: Generally suitable for operation in industrial environments, with a typical range of – 40 °C to + 85 °C, but it is recommended to refer to the detailed documentation for the exact range.
