ABB PM866AK01 Controller

ABB PM866AK01 Controller

Equipment Overview

Core function: PM866AK01 is a compact processor unit of ABB AC 800M series, with control, communication, and redundancy support capabilities, suitable for industrial automation control scenarios, and can be configured through 800xA Control Builder.

Hardware composition: including microprocessor, RAM memory, real-time clock, LED indicator lights, Initiat button, and CompactFlash interface; The base (TP830) is equipped with 2 RJ45 Ethernet ports (CN1, CN2) and 2 RJ45 serial ports (COM3, COM4), where COM3 is the RS-232C port with modem control signal and COM4 is the isolated configuration tool port.

Key features: Supports CPU redundancy (improves availability, covers CPU, CEX Bus, communication interfaces, and S800 I/O), DIN rail quick installation (sliding locking mechanism), each base has a unique Ethernet address (hardware identity identification, can be viewed on the TP830 base label).

Core advantages

Having ISA Secure certification, high reliability, and easy fault diagnosis.

Modular design, supporting gradual expansion and adapting to applications of different scales.

The protection level is IP20 and no additional casing is required; Obtained comprehensive EMC certification.

Support the use of BC810/BC820 to implement segmented CEX Bus, ensuring communication compatibility based on standard hardware such as Ethernet, PROFIBUS DP, etc.

Built in redundant Ethernet communication ports to enhance communication stability.
