Configure input and output (I/O)

analog input: 8 channels, ±0.1% accuracy (suitable for PT100 temperature sensor, 4-20mA current signal)

Digital Input/Output: 16 Channels, 24VDC Isolated signal support (circuit breaker status feedback, thyristor trigger pulse, etc.)

Pulse output: 4 channels, PWM signal output (motor speed control or valve control).

Working environment

Temperature range: -10°C ~ +50°C (explosive atmosphere consistent with UNS2880B-N); can fully adapt to the environment of petrochemical and metallurgy.

Humidity: 5%~95% non-condensing

None Bending sensor: sensitive, anti-jamming performance: IEC 61000-4 certification; Strong anti-jamming ability

Power supply requirements

Main power supply: 220VDC

Redundancy of design: dual power supply module (optional), automatic switching when a failure occurs, to ensure continuous operation of the system.

Real-time control at high-performance

Fast response: The updated processor enables μ level signal processing and can be used for fast excitation of generators (such as demagnetization protection in less than 0.1s).

Intelligent control mode: ABB UNS2880B-P, V2 can process control, communication and diagnosis data simultaneously, and designated core processor is responsible for the task, ensuring the stable operation of the system.

Industrial communication: The ABB UNS2880B-P, V2 supporting protocols are PROFIBUS DP, MODBUS TCP and newly released HART-IP (adapted to industrial Internet of Things).

Power Supply: 85 264V AC, 50/60Hz or 21V 60V DC (typical), built-in battery (for drawer) Extension interface: USB (debugging), optical fiber (redundant communication), easy to connect PLC/DCS and smart devices.

Dual hot-swappable power supplies with redundancy: Provides the ability to automatically switch from main to standby power in the event of failure, reducing any possible downtime.

Fault self-diagnosis: ABB UNS2880B-P, V2 can monitor the status of system CPU, memory and communication in real time, alarm abnormalities and record logs.

Training data: up to October 2023 Z power system: the generator excitation control over 300MW the voltage accuracy is ± 1% and supporting the wind power low voltage ride through (LVRT);

OPC UA protocol through MES system, so that the compressor vibration and reactor pressure of petrochemical production line and other parameters can be monitored in real time;

The new energy of the new smart grid: optimize the reactive power compensation of photovoltaic inverters and improve the stability of the grid.
