Product Introduction

ABB PM864 belongs to AC800M processor series specially developed for ABB System800xA distributed control system. Adopting industrial real-time operating system and mature embedded processor architecture, it features stable operation and powerful expansibility. It can cooperate with S800 series I/O modules and various communication interface cards to build complete control solutions for diversified industrial process control occasions.

Model Interpretation

PM represents processor module; 864 stands for product series and performance grade of AC800M CPU. Complete part number is used for ordering, warehouse management and spare part identification, common alternative code is 3BSE018161R1.

Technical Parameters

Equipped with high-performance 32-bit industrial processor and built-in large-capacity operating memory and solid storage space. Powered by 24VDC backplane power supply with low steady operating power consumption. Working temperature ranges from minus 20 degrees Celsius to plus 60 degrees Celsius, storage temperature covers minus 40 degrees Celsius to 85 degrees Celsius. Applicable relative humidity is 5%~95% without condensation, protection level reaches IP20 for cabinet installation. It supports CPU redundant configuration and can carry large quantity of analog and digital I/O points.

Interface and Communication Configuration

Two independent 10/100M self-adaptive Ethernet ports for TCP/IP, Modbus TCP and upper computer communication. Equipped with isolated RS232/RS485 serial ports for on-site debugging and peripheral device connection. Reserved CEX bus expansion interface to connect S800 I/O base and various communication expansion modules. All communication interfaces adopt anti-interference isolation design to guarantee stable data transmission under complex electromagnetic environment.

Core Functions

Executes high-speed real-time control logic and closed-loop PID calculation to finish process interlock and automatic control. Completes on-site operating data collection, storage and historical data record inquiry. Realizes system fault alarm output and comprehensive module self-diagnosis to feed back abnormal information timely. Supports IEC61131-3 standard programming languages for program compiling, downloading and online debugging. Achieves non-disturbed switching when running under redundant backup mode to improve system safety.

Application Scenarios

Mainly applied in thermal power, hydropower and new energy power plant auxiliary control system. Widely used in chemical industry, oil & gas exploitation, water treatment and papermaking process automation. Suitable for metallurgy, cement production line and large machinery equipment automatic control. Also deployed on intelligent power grid monitoring and urban central heating centralized control projects.

Operation and Maintenance Instructions

Install on standard DIN rail inside control cabinet and keep sufficient surrounding ventilation space. All signal and communication cables select shielded type, separate power cable and signal cable wiring route to avoid crosstalk interference. Finish parameter setting and program download via Control Builder M engineering software before formal running. Check module indicator status and wiring tightness periodically during daily operation. No detachable internal maintenance components, replace whole module directly once hardware permanent damage occurs. Place in dry environment away from severe vibration and corrosive gas.
