ABB UNS0874C:V1 3BHB002651R1 Analog Input Module

Type: Digital plug-in module for signal switch processing, mainly used in high-end testing fields (e.g. communication equipment)

Training data cut < 10/2023

Power: typically accommodates 220V AC/DC or 24V DC.

Input/output points: 16DI/16DO

Signal: pulse signal gain Voice signal output amplitude and precision need to separate configure according to the specific application

Communication interface: need to RS485 interface, data transmission rate of 9600 bit/second

It might be used with other industrial protocols (Modbus, Profinet etc.), but it has to be verified along with a native configuration.

Operating temperature: -10°C to +60°C

Humidity: 85% non-condensing

Communication protocol: Profinet, Profibus.

16-bit Σ-Δ A/D converter, voltage measurement accuracy ±0.1% FS, current accuracy ±0.2% FS

ABB UNS0874C V1 outputs 12-bit PWM signals for PWN frequency applications in the high level spectrum such as servo motors drive.

2.Multi-protocol compatibility

RS485, Modbus RTU/ASCII supported, can be embedded into ABB, Siemens and other brand controllers.

ABB UNS0874C V1 also has a built-in digital filter for filtering 50Hz/60Hz power frequency interference.

Die-cast aluminum alloy housing, IP20 protection, strong anti-vibration and anti-electromagnetic interference.

It features overcurrent protection, monitoring of temperature, dual power supply redundancy (24V DC±20%) and is suitable for ABB UNS0874C V1.

VMEbus standard architecture, support 32-bit/64-bit data transceivers, can cascaded to 16 modules.

Shows LED status indicator and EEPROM fault log storage.

ABB UNS0874C V1 can be used in industries such as power, metallurgy, chemical industry and so on, supporting synchronous generator excitation control, servo motor drive and so on.

Is able to guarantee parameterized configuration (for example PID algorithm) and custom logic via ABB Control Builder F software.

Steel mill drive control system: The control scheme of four-quadrant operation achieving UNS0874C V1 is adopted, the dynamic response speed is increased by 30%, and the annual energy consumption is saved by 1.2 million kWh.

Transformer for excitation in hydropower station: The original analog control is replaced with a new one, the harmonic distortion rate is decreased to 3% from 8% and the stability of generator is also improved a lot.

DCS system: With the DCS system, synchronous control of 16 stirring motors is implemented, and the failure rate is reduced by 60%.
