ABB PM891K01
Product Parameters
- Processor: Utilizes the Freescale PowerQUICC III MPC8641 (contrary to some sources wrongly stating MPC8270) running at 450 MHz. This high – speed processor enables efficient handling of complex control algorithms and data processing tasks, ensuring quick response times for industrial control applications.
- Memory: Equipped with 256 MB of RAM for fast data access during operation, with 208.985 MB available for application – specific tasks. There is also 512 MB of flash memory for storing programs, configuration data, and historical records. Additionally, 16 MB of flash PROM is dedicated to firmware storage.
- Communication Ports:
- Ethernet: 2 Ethernet ports (10/100 mbit/s) for high – speed network communication. These ports are crucial for connecting to local area networks, enabling remote monitoring and control, and facilitating seamless data transfer within the industrial control system.
- Serial: 2 RS – 232/485 ports for serial communication. One of the RS – 232 ports (COM4) is an RJ – 45 female (8 – pole), opto – isolated port with a baud rate of 9600, and it does not support RTS – CTS. This port is used for connecting to specific devices that rely on serial communication protocols, such as certain sensors or legacy equipment.
- Power Supply: Operates on 24 VDC, with an input voltage range of 19.2 – 30 VDC. The power consumption at +24 V is typically 660 mA and can reach a maximum of 750 mA, with a power dissipation of 15.8 W (18 W max). It also has a redundant power supply status input.
- Performance: Can execute 1000 boolean operations in 0.043 ms. It supports up to 32 applications per controller, with each application allowing 64 programs and 128 diagrams. There can be 32 tasks per controller, and it offers 32 different cycle times, with the cycle time per application program going down to 1 ms.
