Common Applications
Product Precautions
Within the Mark VIe backup protection path, IS200TPROH1C provides the field termination layer between turbine protection sensors and the dedicated protection I/O module.
- Approved as an accessory terminal board for the IS220PPROS1B backup turbine-protection I/O module.
- Accepts potential-transformer inputs from 0 to 138 V ac at 5 to 66 Hz.
- Accepts speed inputs in the documented -15 to +15 V dc range.
- Provides 24 V dc, 25 mA speed-sensor power in the certified configuration.
The PT inputs, speed pickups and their sensor-power circuits belong to the dedicated backup protection path and must remain matched to the associated IS220PPROS1B module.
Important Notice: Confirm the complete IS200TPROH1C revision, associated IS220PPROS1B module, terminal assignments, field isolation and protection-system redundancy before installation.

Backup speed protection
Terminates the documented speed-sensor circuits used by the backup protection assembly.
Potential-transformer inputs
Brings certified 0-138 V ac, 5-66 Hz PT signals into the protection path.
Sensor excitation
Provides the documented 24 V dc, 25 mA speed-sensor power boundary.
Certified Mark VIe assembly
Operates as an accessory terminal board for the IS220PPROS1B I/O module.
Read the applicable product and site instructions before work. Verify IS200TPROH1C, the installed host and every connected interface before isolation or replacement.
1
Match IS200TPROH1C to the recorded Mark VIe backup protection assembly and full board revision.
2
Identify the associated IS220PPROS1B module and protection-channel assignment.
3
Record every PT circuit, speed pickup, shield, terminal and sensor-power conductor.
4
Isolate protection wiring using the approved turbine trip-system maintenance procedure.
5
Protect terminal blocks and keyed connectors; do not substitute an adjacent TPRO revision by appearance.
6
Restore PT polarity, speed-sensor polarity, shields and 24 V dc sensor power exactly as recorded.
7
Review protection-module diagnostics and validate healthy input values before enabling trip logic.
8
Complete the controlled backup-protection functional test and retain the acceptance record.
Technical notes
Verify the complete IS200TPROH1C revision, associated IS220PPROS1B module, terminal assignments, PT and speed-sensor wiring, supply isolation and protection-system redundancy before removal or return to service.
