GE IS200DTCIH1ABB Simplex DIN-Rail Mounted Contact Input Terminal Board

د.إ8,888.00

GE IS200DTCIH1ABB Simplex DIN-Rail Mounted Contact Input Terminal Board (DTCI) is a specialized Printed Circuit Board (PCB) used in the GE Speedtronic Mark VI Turbine Control System.

Its core function is to serve as a compact, field-wiring interface for dry contact inputs (digital signals), providing isolation and conditioning before the signals are sent to the main processor.

🧠 Key Functions and Features

The DTCI board is the smaller, DIN-rail mounted equivalent of the larger TBCI (Terminal Board, Contact Input) board, scaled specifically for 24 V DC systems.

  • Function: It is a Simplex Contact Input terminal board with Group Isolation for industrial digital signals.
  • System Application: Used in the Simplex (non-redundant) configuration of the GE Mark VI system.
  • Input Capacity: It features 24 dry contact input channels.
    • 21 circuits operate on a nominal current of 2.5 mA.
    • 3 circuits (typically 22 through 24) operate on a nominal current of 10 mA, which allows for interfacing with external solid-state output devices.

The GE IS200DTCIH1ABB Simplex DIN-Rail Mounted Contact Input Terminal Board (DTCI) is a specialized Printed Circuit Board (PCB) used in the GE Speedtronic Mark VI Turbine Control System.

🧠 Key Functions and Features

The DTCI board is the smaller, DIN-rail mounted equivalent of the larger TBCI (Terminal Board, Contact Input) board, scaled specifically for 24 V DC systems.

  • Function: It is a Simplex Contact Input terminal board with Group Isolation for industrial digital signals.
  • System Application: Used in the Simplex (non-redundant) configuration of the GE Mark VI system.
  • Input Capacity: It features 24 dry contact input channels.
    • 21 circuits operate on a nominal current of 2.5 mA.
    • 3 circuits (typically 22 through 24) operate on a nominal current of 10 mA, which allows for interfacing with external solid-state output devices.
  • Excitation Voltage: It is specifically scaled for 24 V DC systems, with an excitation range of 18 to 32 V DC.
  • Processor Interface: It connects to the main contact input processor board, typically the VCCC (VME Contact Controller) or VCRC board, using a single cable (usually a 37-pin connector).
  • Scalability: Up to two DTCI boards can be connected to a single VCCC or VCRC processor board, allowing for a total of 48 contact inputs.
  • Signal Conditioning: The board includes filters to reduce high-frequency noise and surge suppression circuitry to protect the inputs.
  • Isolation: The input signals are routed to the processor board, where they undergo optical isolation to prevent ground loops and interference before being transmitted to the main controller.

🛠️ Design and Mounting

  • Mounting: It is designed for DIN-rail mounting and features the ability to be vertically stacked to optimize space within the control cabinet.
  • Field Connections: It uses permanently fixed Euro-Block style terminal blocks for connecting field wiring (typically #18 AWG).
  • Revision: The suffix H1ABB specifies the functional and artwork revisions of the board, confirming its revision level within the IS200 series.

The IS200DTCIH1ABB is essential for reliably bringing status and trip signals (like limit switches, pushbuttons, and auxiliary contacts) from the field into the Mark VI turbine control system.
