Diagnostics & Monitoring
Features:
- 8 independent differential analog input channels
- Standard -30 mV to +75 mV linear voltage ranges or diverse thermocouple inputs
- High-performance 15-bit conversion resolution
The module supports configuring the 8th channel for cold junction compensated (CJ) measurements, integrates open/closed-circuit hardware diagnostics, and is Class 1 Div 2 / Zone 2 industrial explosion-proof safety certified. It requires rail mounting and wiring using standard mounting brackets (MTUs) such as TU810 and TU812.
Featuring extremely high channel density and G3-level corrosion protection, the AI835A is directly compatible with various standard thermocouples, including B, C, D, E, J, K, L, N, R, S, T, and U, and is widely used in high-precision temperature monitoring applications in power, petrochemical, and metallurgical industries.
The AI835A 3BSE051306R1 ABB Analog Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
To complete the installation within the control cabinet, the AI835A module must be installed on a compatible Module Termination Unit (MTU).
Factory-certified MTU bases include: TU810 / TU812 / TU814 / TU818 / TU830 / TU833 (available in compact or extended terminal blocks).
Mechanical Failure Protection: Employs factory hardware failure protection code "BA" to prevent accidental insertion of the wrong module type into the MTU slot.
This module has built-in diagnostic functions that can automatically detect field loop faults before data corruption occurs:
Front Panel LED Indicators: Real-time tracking of equipment status via dedicated F (Fault), R (Run), and W (Warning) indicators.
Monitoring Alarms: Automatically flags local system faults, including open circuits, insufficient power, and cold junction temperatures exceeding the range (< -40°C or > 100°C).
