ABB EI811F 3BDH000020R1 Ethernet Module

Power Supply Voltage: 24V DC (supports redundant power input to improve the anti-fault capability of the system).

Signal Types: Supports multiple high-precision analog inputs, including:

Number of Channels: Usually 8 channels (subject to the official manual), with electrical isolation design between channels to reduce cross-interference.

Resolution: 16-bit (can capture tiny signal changes, such as a temperature fluctuation of 0.05°C, meeting high-precision measurement requirements).

Sampling Rate: The typical sampling rate of a single channel is ≥10Hz (can be higher in some scenarios, responding quickly to dynamic processes).

Operating Temperature Range: -40°C to +70°C (adapting to high and low-temperature industrial on-site environments, such as outdoor control cabinets or high-temperature workshops).

Protection Rating: IP20 (suitable for installation in control cabinets, avoiding direct contact with dust and liquids).

Installation Method: DIN rail mounting (complies with industrial standards, facilitating quick integration into control system cabinets).

Communication Interface: Communicates with the upper-level control system through ABB's dedicated internal bus (such as S800 I/O bus) to realize real-time data upload.

Isolation Voltage: Isolation voltage between channels ≥250V AC (enhancing anti-electromagnetic interference capability to adapt to complex industrial electromagnetic environments).

Accuracy Class: ±0.1% FS (full-scale accuracy, ensuring measurement accuracy during long-term operation).

Chemical and Pharmaceutical Industry: Collect high-precision temperature of reaction kettles (such as ±0.1°C control in drug synthesis processes), pressure of high-pressure pipelines, micro-flow and other signals to ensure the consistency of chemical reactions and drug quality.

Metallurgy and Materials Industry: Monitor high-precision temperature of steelmaking furnaces and rolling mills (such as rolling temperature of special steel), pressure of hydraulic systems, etc., to ensure stable material performance.

Energy and Power Industry: Used for high-precision monitoring of steam turbine winding temperature in power plants, boiler superheated steam pressure, and temperature of new energy equipment (such as photovoltaic inverters), avoiding equipment failures caused by minor parameter abnormalities.

Precision Manufacturing: In the production of semiconductors and electronic components, collect high-precision parameters such as clean room ambient temperature, humidity, and gas flow to ensure a stable production environment.

Scientific Research and Laboratories: As an industrial-grade high-precision data acquisition device, it is used in scenarios such as simulation experiments and process simulation to provide reliable raw data support.
