ABB GJR2368900R1348 87TS01K-E coupling module

ABB GJR2368900R1348 87TS01K-E coupling module

I. Basic Product Information
Original part number: GJR2368900R1348 
Board card model: 87TS01K-E
Ownership system: ABB Procontrol P14 power station-specific DCS control system
Equipment type: 16-channel high-precision temperature acquisition input card (Temperature Input Module)
Origin: Swedish factory
Core positioning: Specifically designed for massive temperature measurement points in power plants, compatible with both thermal resistance and thermocouple temperature sensors, collecting temperature signals and converting them into digital bus data for upload to the P14 main controller. It is the main IO card for bearing, stator, and pipeline temperature measurement of the unit.

Core Functional Features
16 independent temperature measurement channels, with software allowing free switching between RTD (resistance temperature detector) and TC (thermocouple) signal types
On-board high-precision 24-bit ADC analog-to-digital conversion, built-in cold junction compensation (CJC), no temperature drift error for thermocouples
Support for 2-wire/4-wire RTD wiring, automatic identification of broken wires and reporting of alarms
Channel groups are electrically isolated, capable of withstanding power plant excitation, frequency conversion, and high-voltage strong electromagnetic interference
6U European standard plug-in card, P14 rack supports hot-swappable replacement, with short maintenance downtime
Full-time hardware + firmware self-diagnosis, panel LED provides intuitive display of power, operation, channel faults, and bus status
Mechanical error-proof insertion keys, preventing incorrect insertion of other model IO boards and damaging the backplane
Built-in signal filtering to suppress 50/60Hz power frequency interference, suitable for the complex electromagnetic environment of power plants
