Features:

  • Interface Between Field Contact Input Devices and the Mark VI/VIe Control System Backplane
  • Integrates Capability of Contact Signal Conditioning with Simplex Input Acquisition
  • Functions in Conjunction with the TMR and Simplex I/O Modules Within the Control Architecture
The IS200STCIH2AED operates as the Simplex Contact Input (STCI) terminal board in GE Mark VI and Mark VIe control racks, providing reliable digital input processing for all contact-based field devices connected to the system. It continuously receives discrete contact signals from external equipment and converts these raw inputs into conditioned digital signals distributed through the rack backplane to support steady state operation of the control processor and I/O modules.

The IS200STCIH2AED provides essential input functions common to the entire contact monitoring path, and is a critical component of the discrete signal acquisition chain, directly affecting the proper, normal operation of the overall control system. One IS200STCIH2AED terminal board is required per simplex contact input channel group depending on the desired I/O density. The IS200STCIH2AED occupies a dedicated terminal board slot in the rack and interfaces with the corresponding STCI processor board located in the adjacent slot position.

For expanded contact input applications, the Mark VI/VIe System requires additional IS200STCIH2AED terminal boards installed in subsequent I/O slots. In addition to standard single board operation, the IS200STCIH2AED configuration also supports parallel input processing. The IS200STCIH2AED input acquisition executes signal validation using the internal circuitry specified in the terminal board specifications.

The IS200STCIH2AED General Electric Simplex Contact Input (STCI) terminal board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Excitation Voltage: Provides 24 VDC or 125 VDC contact excitation voltage directly from the board to power the field contacts.
  • Mounting Design: Mounts vertically on a standard DIN-rail or directly onto a cabinet backpanel sheet.
  • Wiring Termination: Supports standard industrial wire sizes up to 12 AWG via two fixed terminal blocks.
  • Hardware Configuration: Requires manual configuration of plug jumpers to select between 24 VDC and 125 VDC excitation modes.
  • Hot-Swapping Limits: Designed for modular replacement, but requires control system isolation before disconnecting active 50-pin cables.
Description
The IS200STCIH2AED is a simplex (single-channel) contact input terminal board developed by General Electric (GE) under the Mark VI series, specifically designed for compact contact input applications. The board supports DIN rail or flat-panel mounting and provides 24 contact inputs, with nominal excitation voltages externally supplied at 24 V, 48 V, or 125 V DC, meeting diverse process control requirements. The input circuits feature surge protection and high-frequency noise suppression to ensure stable and reliable signal performance.

The IS200STCIH2AED is compatible with the PAiC I/O Pack, with I/O modules connected via D-type connectors and communicating with the controller over Ethernet. It is intended only for simplex systems, providing a reliable contact input interface for distributed control systems. The board’s compact design makes it suitable for high-density installation environments.

For installation, the STCI board is typically mounted on a metal bracket with a plastic insulating spacer and then fixed onto a DIN rail as a whole; alternatively, it can be installed directly on a metal mounting plate with an insulating spacer and secured to the cabinet with bolts. Contact inputs are usually wired directly to the terminal strip using 18 AWG wires, and the shielding layer should be grounded on an independent bracket to ensure signal integrity. The IS200STCIH2AED features a right-angle pin header, compatible with various commercially available plug-in terminal strips, providing a total of 52 terminals for convenient wiring and maintenance.
