GE IS230TCISH7C
Product Name: GE Mark VI High-Density Thermocouple Interface Terminal Board
Introduction: A signal-conditioning and wiring terminal board for Mark VI/Mark VIe turbine exhaust, bearing, and casing thermocouples.
Technical Specifications:
-
Channels: 24 configurable thermocouple inputs (typical build)
Detailed content
-
Types: J, K, T, E, N, R, S, B
-
Cold-Junction Compensation: Onboard sensor, ±0.5 °C
-
Accuracy: ±0.5 °C typical including CJC
-
Scan Rate: ≥ 4 Hz/channel
-
Isolation: 1500 V AC channel-to-backplane
-
Connectors: 2 × 37-pin D-sub female to I/O pack, barrier screw terminals to field
-
Temperature: 0 °C to +60 °C
Functional Features: Open/short detection, software filter 1–100 Hz, auto-zero calibration, noise rejection.
Working Principle: TC EMF → input filter → CJC correction → ADC on associated I/O processor → backplane data transfer.
Materials: FR-4 PCB with conformal coat, stainless screw terminals, anodized aluminum mounting bracket.
Installation: Secure in Mark VI I/O chassis, connect D-subs to TCIA pack, use twisted-pair TC extension wire with same alloy compensating cable.
Precautions: No copper wire for TC extension; keep away from VFD output cables; verify CJC jumper setting before commissioning.
