Features:

  • Interface Between Field Thermocouple Sensors and ABB Control System Backplane
  • Combines Capability of Multi-Channel Analog Signal Conditioning with 12-Bit Precision Conversion
  • Operates in Conjunction with ABB AC 800M Controllers and S800 I/O Series Modules
The AI635 3BHT300032R1 operates as the Analog Input Module in an ABB distributed control system, providing reliable thermocouple signal acquisition for all temperature monitoring applications within the system. It continuously receives incoming low-level thermocouple signals through 14+2 dedicated channels and converts these analog inputs to digital data with 12-bit resolution, distributing the processed temperature information through the rack backplane to support steady state operation of all controllers and I/O modules.

The AI635 3BHT300032R1 provides essential analog input functions common to the entire temperature monitoring path, and is a critical component of the measurement chain, directly affecting the proper, normal operation of the overall thermal control system. One or more AI635 3BHT300032R1 modules are required per rack depending on the desired channel density and monitoring coverage.

For expanded temperature monitoring applications, the ABB System requires additional AI635 3BHT300032R1 analog input modules installed in available I/O slots. In addition to standard single module operation, the expanded configuration also performs distributed signal acquisition. The ABB multi-module configuration executes parallel processing using the internal bus architecture specified in the I/O options.

The AI635 3BHT300032R1 ABB Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
