Description

The GE IS200STCIH2A Simplex Contact Input Terminal Board is a compact field interface module developed for the Mark VIe and Mark VIeS turbine control platforms. It accepts 24 dry contact inputs from switches, relays, and other field devices operating with 24 VDC, 48 VDC, or 125 VDC excitation supplied by an external source. The board conditions and filters these signals before passing them to a compatible PDIA I/O Pack, which converts the inputs to digital data and transmits them to the controller over Ethernet.

Designed specifically for simplex control architectures, the IS200STCIH2A incorporates surge suppression, high-frequency noise filtering, and resettable current protection to ensure dependable operation in harsh industrial environments. Its DIN-rail or flat-panel mounting options and pluggable terminal blocks simplify installation and maintenance in gas turbines, steam turbines, and balance-of-plant control systems.

Information

Overview Manuals Application Notes Product Applications Mechanical Installation & Insertion

Features:

  • 24 dry contact input channels
  • Supports 24, 48, and 125 VDC field excitation
  • Compatible with IS220PDIA I/O Pack
  • Ethernet communication via I/O Pack
  • Integrated surge and EMI suppression
The GE IS200STCIH2A is a simplex contact input terminal board for GE Mark VI and Mark VIe Speedtronic turbine control systems. It provides the interface between field contact devices (switches, relays, limit switches) and the turbine control system processor.

The board accepts dry contact inputs, typically 24 in number, with optical isolation between field inputs and the control system electronics. Input voltage is configurable for 24 V DC or 125 V DC depending on application requirements. Hardware debounce filters ensure reliable contact status detection with a typical response time of 2 ms.

The IS200STCIH2A GE Simplex Contact Input Terminal Board may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The IS200STCIH2A mounts in the GE turbine control rack and communicates with the main processor via I/O packs or direct cabling using the proprietary GE Speedtronic communication protocol. Contact status is continuously monitored and fed back to the controller for logic processing and turbine protection.
The board operates in temperatures from 0 to 60°C and carries UL, cULus, and CE certifications. Typical applications include turbine limit switch monitoring, auxiliary contact feedback, alarm contact inputs, and discrete status monitoring in gas turbine, steam turbine, and generator control systems.
  • Gas/Steam Turbine Control: Processes limit switches, relay states, and safety trip signals at high speed
  • Industrial Automation: Interfaces sensors, pushbuttons, and actuators in heavy-duty manufacturing
  • Heavy Process Industries: Deployed in chemical, pharmaceutical, and oil/gas for reliable discrete monitoring
  • Excitation Systems: Used with EX2100 systems for condition monitoring and switchgear verification

Mounting: Secure the STCI board with its plastic insulator onto a sheet metal carrier, then snap it onto a standard DIN rail or bolt the sheet metal assembly directly into your system cabinet.
I/O Pack Insertion: Plug your compatible I/O pack (such as the PAIC module) directly into the 37-pin (female) D-type connector located on the terminal board.
Mechanical Securing: Anchor the pack mechanically using the threaded studs located next to the Ethernet ports and secure them to the terminal board's mounting bracket. Adjust this bracket to ensure zero right-angle force acts on the D-type pin connector.
