GE IS200DTCIH1A DIN-rail Contact Input Card

د.إ8,888.00

GE IS200DTCIH1A DIN-rail Contact Input Card (DTCI) is a Simplex Contact Input with Group Isolation Terminal Board used in the GE Speedtronic Mark VI Turbine Control System.1

Its function is to serve as a compact, field-wiring interface for collecting dry contact digital signals from the field and relaying them to the main Mark VI processor board.

⚙️ Key Functions and Technical Specifications

The DTCI board is the 24 V DC-scaled, DIN-rail mounted equivalent of the larger TBCI terminal board.2

Feature Details
System GE Mark VI Speedtronic Turbine Control System
Function Simplex (Non-redundant) Contact Input Terminal Board with Group Isolation
Input Capacity 24 dry contact input channels
Excitation Voltage Nominal 24 V DC (range is 18 to 32 V DC)
Input Current 2.5 mA nominal current on circuits 1-21; 10 mA nominal current on circuits 22-24 (for solid-state outputs)

Input Current 2.5 mA nominal current on circuits 1-21; 10 mA nominal current on circuits 22-24 (for solid-state outputs)
Processor Interface Connects to the main contact input processor board, typically the VCCC (VME Contact Controller) or VCRC board, via a single cable.
Scalability Up to two DTCI boards can connect to a single VCCC/VCRC board, providing a total of 48 contact inputs.
Signal Integrity Includes filters for high-frequency noise reduction and surge suppression near the signal entry point.
Mounting Designed for DIN-rail mounting using Euro-Block terminal blocks, allowing for vertical stacking to conserve cabinet space.

The board is crucial for reliably bringing status, alarm, and trip signals (like limit switches and pressure switch contacts) from the turbine and balance-of-plant equipment into the control system for high-speed sequence of events (SOE) monitoring and logic processing.
