Process Control and Signal Conditioning
The IS200STTCH2ACA interfaces with the control system to execute cold junction compensation (CJC) via an onboard sensor, correcting raw millivolt data to accurate temperature values. The board provides channel-to-channel isolation through opto-isolators and galvanic isolation, which protects the host control logic from field-side voltage transients. Integrated RC networks provide 50/60 Hz notch filtering to mitigate electromagnetic interference, ensuring signal stability for the Mark VI/Mark VIe I/O packs. The module supports software-selectable thermocouple types (J, K, T, E, R, S, B), allowing for flexible integration into diverse thermal monitoring loops without requiring hardware modifications.
Frequently Asked Questions
Q: Does this terminal board require external power for the CJC sensor?
A: No, the IS200STTCH2ACA draws auxiliary power from the connected I/O pack through the 37-pin D-Sub interface, which also powers the onboard CJC sensors and signal conditioning circuitry.
Q: Is this board compatible with both Simplex and TMR configurations?
A: Yes, the board is engineered for versatility in simplex, dual, or Triple Modular Redundant (TMR) system architectures, provided the associated I/O packs are configured to handle the input data mapping correctly.
Field Installation Guidelines
Mount the IS200STTCH2ACA on a standard TS-35 DIN rail within the control cabinet. Terminate thermocouple field wiring to the 48 screw terminals using #12 to #24 AWG wire, ensuring that polarity is maintained across all 24 channels to prevent measurement errors. Connect the 37-pin D-Sub cable to the corresponding STCC or PAICH I/O pack to establish the communication link. Verify that all cable shields are terminated to the chassis ground bus to minimize noise pickup. Perform a loop check via the Control System Toolbox to validate each thermocouple input channel before system startup.
