Description

ABB A1835A (3BSE051306R1)

Technical Specifications:

  • Model: A1835A
  • Order Code: 3BSE051306R1
  • Channels: Multi-channel analog input
  • Signal Types: Voltage (e.g., 0-10V) and Current (e.g., 4-20mA)
  • Resolution: High-precision 16-bit or higher
  • Isolation: Channel-to-channel and channel-to-ground optical isolation

Functional Features:

  • High-Accuracy Measurement: Exceptionally low temperature drift and linearity error.
  • Strong Noise Immunity: Built-in hardware filtering effectively rejects industrial EMI.
  • Wire Break Detection: Automatically detects open sensor circuits and triggers alarms.
  • HART Transparency: Supports HART protocol passthrough for smart field devices.

Application Scenarios:

  • Process monitoring for temperature, pressure, and level in oil & gas, chemical, and power generation.
  • Environmental monitoring and HVAC systems.
  • Precision manufacturing and quality control processes.

Performance Parameters:

  • Conversion Time: Millisecond-level response.
  • Input Impedance: >1MΩ for voltage inputs.
  • Accuracy: Typically ±0.1% of span.

Material Composition & Structural Features:

  • Terminal Design: Spring-clamp terminals for fast, tool-less wiring.
  • Status Indication: Individual LED indicators per channel for active signal and fault status.
  • Housing: Flame-retardant, anti-static plastic enclosure.

Working Principle:
Analog signals pass through input protection and hardware filtering before being digitized by a high-resolution ADC. The module transmits the digital data to the CI85x communication adapter via the S800 I/O bus.

Installation Requirements:

  • Shielded twisted-pair cables are mandatory for analog signal connections.
  • The cable shield must be grounded at the module end only (single-point grounding).
  • Ensure proper wire stripping length to avoid short circuits.

Usage Precautions:

  • Verify signal type matches hardware jumper or software configuration before powering up.
  • Never apply input signals exceeding the maximum rated range.
  • Keep analog signal cables separated from high-voltage power cables to minimize interference.
