Module Type: RTD Input Terminal Board used in GE Speedtronic Mark VI Control System

Power Input

Power source: Powered through ribbon cable connected to TBCIA / VRTD processor board

Nominal operating voltage: 24 VDC

Power consumption of the board: ≤ 20 mA

Field Signal Inputs

RTD Input Channels: 16 channels, compatible with 2-wire and 3-wire RTD sensors

Supported sensor models: Pt10, Pt100, Pt200, Cu10, Ni120

Excitation current: 1 mA for each channel

Maximum permitted lead resistance: 15 Ω (cable resistance included)

Onboard diagnostic functions: open-circuit detection, short-circuit detection and out-of-range resistance alarm

Input protection: Equipped with built-in noise suppression and surge protection circuits

Internal Interface Outputs

Signal transmission output: Delivers conditioned RTD resistance signals to the VRTD processor board through dual 37-pin ribbon connectors

No field analog outputs and no relay contact outputs for field devices

Additional Information

This terminal board serves as field signal termination and signal conditioning hardware. It cannot conduct independent A/D conversion; temperature computation is undertaken by the matching VRTD module. Channel-to-channel isolation design is adopted to effectively mitigate ground loop interference.

Module Type: RTD Input Terminal Board for GE Speedtronic Mark VI Control System

Safety Precondition: Disconnect all rack power before removing modules or testing field wiring to prevent circuit damage and equipment failure.

1. Pre-fault Visual and Hardware Inspection

Visually inspect the board for burn marks, bloated components, corrosion and damaged terminal blocks. Examine the dual 37-pin ribbon cables connecting the IS200TRTDH1CCC to the VRTD/TBCIA processor board, ensuring full insertion and no bent or damaged pins. Fasten all RTD field terminals, and check for loose wiring, oxidized terminals and damaged cable insulation. Ensure all shielded cables adopt single-point grounding to avoid ground loop interference.

2. Power Supply Inspection

Energize the control rack and measure the 24 VDC working voltage supplied to the terminal board via ribbon cable. Verify the voltage is within the standard operating range, as abnormal voltage input will cause unstable RTD readings or channel malfunction. If no voltage is detected, troubleshoot the upstream TBCIA/VRTD module and backplane connection status.

3.Disconnect field RTD wiring from the terminal board, then test the resistance of sensor cables and RTD elements with a multimeter. An open-circuit alarm is generally caused by broken sensor wires, loose terminals or faulty RTD probes. A short-circuit alarm results from damaged cable

4.Use standard shielded twisted-pair cables for RTD signal transmission, and separate signal cables from high-power cables to reduce EMI interference. Check key parameters in ToolboxST, including sensor type (Pt10/Pt100/Cu10/Ni120), wiring mode and engineering unit settings, as incorrect configuration will lead to persistent measurement offset. Inspect field junction boxes for loose terminals, water ingress and other intermittent faulty conditions.

5. Communication Fault Troubleshooting Between TRTD and VRTD Module

Perform a rack power cycle to eliminate temporary communication anomalies. Swap ribbon cables between normal and faulty channels to exclude cable damage faults. Check module identification status via ToolboxST; if the system fails to recognize the IS200TRTDH1CCC, inspect the backplane signal contacts for poor connection or contamination.

6. Software Diagnostic Verification

Access ToolboxST software to query channel quality status, open/short circuit alarms and out-of-range fault records. Clear historical fault logs after resolving physical faults, and conduct continuous channel monitoring to verify stable operation. Complete calibration verification with precision resistance standards during equipment downtime.

7. Module Replacement Verification

After excluding faults in field wiring, RTD sensors and ribbon cables, replace the IS200TRTDH1CCC with a fully functional spare module. If the system and all measurement channels return to normal operation, the original terminal board has internal circuit failure and needs to be replaced.
