ABB AI830A RTD Input Module

ABB AI830A RTD Input Module

DESCRIPTION

The AI830/AI830A RTD Input Module has 8 channels for measurement of temperature with resistive elements (RTDs). With 3-wire connections. All the RTDs must be isolated from ground.

The AI830/AI830A can be used with Pt100, Cu10, Ni100, Ni120 or resistive sensors. Linearization and conversion of the temperature to Centigrade or Fahrenheit is performed on the module.

Every channel can be individually configured. The MainsFreq parameter is used to set mains frequency filter cycle time. This will give a notch filter at the frequency specified (50 Hz or 60 Hz). 

FEATURES

8 channels for RTD (Pt100, Cu10, Ni100 and Ni120 and resistor) inputs

3-wire connection to RTDs

14 Bit resolution

Inputs are monitored for open-circuit, shortcircuit and has a input grounded sensor

Basic Overview

Model and function: AI830A is an RTD input module with 8 channels from ABB. Each channel supports Pt100, Cu10, Ni100, Ni120 or resistance sensors.

Connection: The module uses a 3-wire connection to the RTD to ensure the accuracy of the measurement.

Technical characteristics

HIGH RESOLUTION: The AI830A provides 14-bit resolution to accurately measure temperature values.

Linearisation and Conversion Functions: The module has built-in linearisation and temperature to Celsius or Fahrenheit conversion functions, making it easy for users to directly obtain the desired temperature units.

Independent Configuration: Each channel can be individually configured to meet the needs of different application scenarios.

Monitoring and Protection Functions: Inputs are monitored for open and short circuits and have input ground sensors to ensure measurement reliability and safety.

Power supply frequency filter: The MainsFreq parameter is used to set the power supply frequency filter cycle time, providing a 50Hz or 60Hz trap filter to reduce the impact of power supply frequency on the measurement.

Precautionary note

Installation and Commissioning: Installation and commissioning should be carried out by professional personnel to ensure that the module is correctly connected and configured.

Maintenance and Inspection: Regular maintenance and inspection of the module to maintain its normal operating status.

Safety norms: In the process of use should comply with the relevant safety norms and operating procedures to ensure the safety of personnel and equipment.
