ABB PP902CE101 3BHE028989R010 Dual Gigabit CPU Controller for AC800M DCS

Product Description

PP902CE101 with material code 3BHE028989R010 belongs to ABB PPC902 CPU series, a rack-mounted industrial controller for AC800M PAC and System 800xA DCS, made in Switzerland.

It adopts ARM Cortex-A9 dual-core 1GHz processor, equipped with 512MB DDR3 RAM, 2GB eMMC flash and 2MB FRAM non-volatile memory. It supports large I/O logic, multi-loop PID control, 

batch recipe management and historical data recording, widely applied in power, chemical, pulp and water treatment industries.

Front panel carries dual gigabit Ethernet, RS232, RS485 and dual USB ports, supporting Modbus TCP/RTU, IEC 104, ABB native control protocol and OPC UA. It supports hot standby 

CPU redundancy for non-stop production switching, and complies with IEC 62443 SL3 industrial cybersecurity standards with secure boot and access permission management.

The PCB is conformal coated against dust, humidity and vibration. Single-slot plug-in design fits standard AC800M backplane, serving as critical replacement spare for large process control racks.
