ABB AI801 Analog Input Module (3BSE020512R1)

A robust 8-channel module for the S800L system, designed to reliably read standard 0-20 mA and 4-20 mA signals from field instruments in industrial automation and process control applications.

Core Features & Benefits

  • 8 Isolated Channels: Handles eight 0-20 mA or 4-20 mA signals, with the entire group isolated from ground for enhanced noise immunity and safety.
  • Built-in Protection: Inputs are secured against short circuits to the power supply (up to 30 V DC) without damage, using a PTC resistor for current limiting.
  • HART Communication Compatible: The input circuitry supports and withstands HART protocol signals superimposed on the 4-20 mA loop.
  • High Accuracy & Resolution: 12-bit resolution with a maximum error of 0.1% ensures precise measurement and control.

Technical Specifications

  • Article Number: 3BSE020512R1 AI801
  • Signal Input: 0-20 mA, 4-20 mA DC, Unipolar
  • Input Impedance: 230 - 275 kΩ (Current input, PTC included)
  • Update Cycle: 1 ms
  • Max Input Voltage: 30 V DC (Non-destructive)
  • Power Consumption: 1.1 W (70 mA from +5V Modulebus, 30 mA from +24V external)
  • Operating Temperature: 0 to +55 °C (For vertical mounting: max 40 °C)
  • Connections: Via detachable connectors for easy installation and maintenance.
  • Certifications: CE, cULus, ATEX Zone 2, and Marine (ABS, BV, DNV, LR).

Typical Applications

This module is ideal for interfacing with a wide range of 4-20 mA field devices, including:

  • Pressure and Temperature Transmitters
  • Flow Meters and Level Sensors
  • Valve Positioners
  • Other Process Control Instruments
