Product Overview

The General Electric IS200TTSAG1A is a turbine emergency trip board used in Speedtronic Mark VIe control and protection cabinets. It supports the acquisition and conditioning of temperature-related protection signals so the control system can evaluate turbine health and initiate protective actions when configured thresholds are exceeded. This board is typically applied where temperature inputs are part of shutdown permissives, alarms, or emergency trip logic for critical turbine sections.

Some listings describe this part as a “trip” board while also listing temperature-conditioning functions. In practice, the role of the IS200TTSAG1A should be confirmed against the cabinet I/O design and the associated terminal wiring to ensure the correct sensor type and channel mapping.

Signal Conditioning and Hardware Characteristics

• Commissioning notes

• Validate sensor type, range, and channel assignment in the control configuration before energizing

• Use ESD controls and verify all terminations are correctly torqued

• Safety-related trip functions must be tested per site procedures after replacement

Industrial Applications

• Gas and steam turbine protection cabinets where temperature points are used for shutdown and permissive logic

• Monitoring of bearings, exhaust/metal temperatures, and auxiliary skid temperature interlocks (system dependent)

• Replacement spare for Mark VIe installations requiring original temperature-conditioning/trip I/O hardware

• Modernization and maintenance programs focused on reducing nuisance trips through stable, diagnosed sensor inputs
