Functional Description

IC3600SIIA9 is an Isolated Input Filter Card developed by GE. It is a part of Mark I and II control system. It filters out electrical noise and unwanted signal variations, ensuring that only clean and stable signals are passed on for further processing.

Features

The SIIA card plays a critical role in the control system by providing electrical isolation and signal filtering for high-level input signals. Specifically, it is designed to interface with signals in the range of 125 Volts DC, or 115 Volts AC.

These types of signals typically originate from field devices such as switches, relays, or other equipment used in turbine and auxiliary systems. The purpose of isolating and filtering these signals is to:

  • Protect downstream electronics from voltage spikes, noise, and surges
  • Improve signal quality and reliability before further processing
  • Prevent ground loops and ensure safe system operation

Output and Compatibility

  • After conditioning, the output from the SIIA card is tailored to be compatible with the LIBB (Low-voltage Input Buffer) card, another component within the Mark I/II systems. The SIIA outputs a 12-volt signal, which is the standard input level expected by the LIBB card for further logical processing.
  • This structured signal path ensures clean, isolated signal transitions from field devices to the control logic circuitry, maintaining the integrity and performance of the turbine control system.
