Description
The IS200TBTCH1C is a high-density Thermocouple Input Terminal Board designed for the General Electric Mark VIe distributed control system. This board serves as the primary interface between field-mounted thermocouple sensors and the system's I/O processor packs. It is engineered to support mission-critical turbine control applications, providing reliable signal acquisition for 24 independent channels. The board is compatible with multiple thermocouple types, including E, J, K, S, and T, and supports flexible system architectures ranging from simplex to triple modular redundant (TMR) configurations.
Features
- Supports 24 independent thermocouple input channels.
- Compatible with thermocouple types E, J, K, S, and T.
- Direct interface for PTCC I/O packs via onboard J-type connectors.
- Supports Simplex, Dual, and TMR system configurations.
- Integrated shield terminal strips for improved noise immunity and signal integrity.
- Accommodates field wiring up to 12 AWG via barrier-type terminal blocks.
Applications
The IS200TBTCH1C is specifically designed for use in GE Mark VIe control systems, primarily found in power generation, turbine control, and heavy industrial process monitoring where high-precision temperature measurement and system redundancy are required.
