Description
Product Description
The PM891K01 3BSE053241R1 ABB processor unit serves as the core processing unit of the System 800xA distributed control system,responsible for executing various control,monitoring,and automation tasks.
feature
Reliability and simple fault diagnosis program
Modular,allowing for gradual expansion
IP20 category protection without attachment
The finance director has comprehensive EMC certification
High performance and large application memory
Using a pair of BC810
Built in redundant Ethernet communication ports
The PM891K01 3BSE053241R1 processor is a single-chip unit equipped with a power supply,power board,and terminal.This unit includes a microprocessor and RAM memory,real-time clock,LED indicator,input button,and secure digital interface.PM891K01 3BSE053241R1 does not contain any internal batteries.PM891K01 3BSE053241R1 has two RJ45 Ethernet ports(cn1,cn2)and one RJ45 serial port(COM4)for connecting to the control network.The C4 port is isolated and used for configuration tools.PM891 supports higher availability CPU redundancy(CPU,CexBUS,communication interface,and S800 I/O).
The communication extension bus(CexBUS)is installed on this unit.CexBUS is used to expand airborne communication ports with communication interface units.It is possible to use redundant communication interfaces.The CexBUS interconnect unit BC810 is used to increase the availability of CexBUS by dividing it into separate parts.The optical module of this device can be used to connect a cluster of 7 S800 I/O units(each unit can contain up to 12 units).Each PM891 provides a unique Ethernet address to provide hardware identification for the unit.
application area
The PM891K01 3BSE053241R1 ABB processor unit is suitable for complex control and automation applications in industries such as oil and gas,power generation,and chemical processing.
