STB-TCI

Sensor And Detector Interfaces Overview

The STB-TCI is an obsolete isolated thermocouple panel from Analog Devices designed for the RTI-820 data acquisition system. It provides eight input channels with 750 V rms channel-to-channel and channel-to-system isolation. The unit supports standard thermocouple types (J, K, T, E, R, B, S) with cold junction compensation accuracy of ±1°C. User-selectable gains include 50, 100, 200, and 1000, corresponding to input ranges of ±5 mV, ±25 mV, ±50 mV, and ±100 mV. A 4 Hz low-pass filter reduces noise, and break detect circuitry identifies disconnected sensors. Power requirements are +5 V at 300 mA.

Sensor And Detector Interfaces Feature Summary

• Provides high electrical isolation for low-level voltage signals in noisy environments
• Includes user-selectable gain settings and cold junction compensation for thermocouples
• Features quick-disconnect screw terminals for easy field installation and replacement

Sensor And Detector Interfaces Applications

• Data acquisition systems requiring high isolation for thermocouple inputs
• Harsh industrial environments with large common-mode voltages
• Applications needing simultaneous monitoring of multiple low-level sensor signals

Sensor And Detector Interfaces Procurement Notes

This component is officially marked as obsolete by Analog Devices. Verification should focus on historical datasheets and compatibility with legacy RTI-820 systems. Ensure that any procurement involves verified surplus stock or authorized distributors handling end-of-life inventory. Confirm physical dimensions and pinout compatibility before integration into existing setups.

Sensor And Detector Interfaces Selection Notes

Select the STB-TCI when high electrical isolation is required for thermocouple applications interfacing with the RTI-820. It serves as a direct alternative to the non-isolated STB-TC panel. Consider this model over modular 5B Series solutions if single-channel modularity is not required but high channel density with isolation is necessary.

Sensor And Detector Interfaces Part Context

The STB-TCI belongs to the Analog Devices multiplexed analog signal conditioning panel family. It is designed to work exclusively with the RTI-820 board using the standard multiplexed analog bus. It shares interchangeable addressing schemes and physical dimensions with other panels like the STB-HLI and STB-TC, allowing mixed configurations within the same rack mount system.

Sensor And Detector Interfaces Replacement Considerations

Public confirmed substitute part numbers: None available. The STB-TCI is obsolete. For isolated thermocouple inputs, consider using the 5B02 panel populated with 5B37 modules.
