The GE IS200STCIH2AED is a Simplex Contact Input Terminal Board designed for the Mark VIe and Mark VIeS turbine control platforms. This interface module serves as a field connection point, accepting 24 discrete contact inputs from external devices such as relays, switches, and limit sensors. It is engineered to condition and filter these signals before they are processed by a compatible PAIC I/O pack.

Features

  • Designed for simplex control architectures in Mark VIe/VIeS systems.
  • Supports 24 VDC, 48 VDC, and 125 VDC external excitation voltages.
  • Integrated surge suppression and high-frequency noise filtering for signal integrity.
  • Utilizes resettable polymer (PTC) fuses for overcurrent protection.
  • Compatible with PAIC I/O packs via a D-type connector interface.
  • Compact design suitable for DIN-rail or flat-panel mounting.

Applications

  • Gas and steam turbine control systems.
  • Generator set monitoring and protection.
  • Balance-of-plant (BOP) control logic.
  • Critical production line status monitoring and alarm feedback.

Installation Guidelines

  • Ensure the control system power is disconnected before installing or removing the terminal board.
  • The board is typically mounted on a sheet metal carrier, which is then secured to a standard DIN rail.
  • Use shielded cabling for field inputs to minimize EMI/RFI interference in high-noise industrial environments.
  • Verify that the external excitation voltage matches the configured input range to prevent damage to the sensing circuits.
  • Maintain adequate clearance around the module to ensure proper airflow and cooling.

FAQs

What is the primary function of the IS200STCIH2AED?

It acts as a terminal board for the Mark VIe system, providing signal conditioning and surge protection for up to 24 contact inputs before they are digitized by the I/O pack.

Does this board include the I/O pack?

No, the IS200STCIH2AED is a terminal board only. It requires a separate PAIC I/O pack, which connects to the board via a D-type connector.

How do the resettable fuses function?

The board uses PTC (positive temperature coefficient) fuses. If a fault causes current to exceed 0.5A, the fuse limits the current; once the fault is cleared, the device cools and automatically resets, requiring no manual replacement.
