ABB PM861K01 3BSE018105R1 Technical Specifications
Core Processing & Memory
Microprocessor Type: 32-bit high-speed RISC processor (operating at 48 MHz)
Onboard Memory: 16 MB of high-speed RAM (with ECC/Error-Correcting Code protection) and 4 MB of non-volatile Flash Memory.
Memory Backup: Built-in battery backup slot to safeguard volatile application data during prolonged power outages.
Inputs, Outputs & Communication Interfaces
Built-in Interfaces: 2×RS-232C serial ports (isolated for connecting programming tools or third-party Modbus devices).
Control Network Ports: 2×Ethernet ports (ModuleBus/Control Network) supporting twisted-pair connectivity for fully redundant peer-to-peer or server communication layouts.
I/O Capacity: Supports direct expansion via high-speed ModuleBus interfaces for local S800 I/O modules, or connection to remote I/O via PROFIBUS DP, Foundation Fieldbus, or PROFINET interfaces.
ABB PM861K01 3BSE018105R1 Product Advantages & Key Features
Native Redundancy Support: Easily configured as a synchronized redundant pair (Primary and Backup CPUs). In the event of a primary processor failure, switchover happens smoothly in milliseconds without bumping or interrupting the active process.
Online Hot-Swappability: The module can be safely plugged into or removed from its baseplate while the system rack remains powered, drastically minimizing process downtime during upgrades or servicing.
High Electromagnetic Compatibility (EMC): Built with heavy industrial-grade shielding that exhibits exceptional immunity to high-voltage transients, electrical noise, and radio-frequency interference (RFI).
Comprehensive Self-Diagnostics: Embedded with advanced continuous system self-supervision routines, including memory integrity audits, temperature tracking, and detailed event logging transmitted instantly to the centralized HMI.
ABB PM861K01 3BSE018105R1 Wiring & Electrical Characteristics
Input Voltage Power Supply: 24 V DC (Accepts a safe operating range of 19.2 V DC to 30 V DC).
Current Consumption: Typically draws 0.35 A to 0.50 A at 24 V DC.
Wiring Connection Method: Spring-terminal or screw-terminal blocks integrated into the accompanying TP830 baseplate. Designed for high-density, vibration-resistant wire termination supporting wire sizes from 0.2 mm² to 2.5 mm² (AWG 24 to AWG 12).
