Functional Description

IC3600SLEH1F is a Logic Element Card manufactured by GE Fanuc. It is a part of Mark I and II used in gas turbine control systems. This card forms an essential part of the turbine’s control logic hardware, responsible for implementing specific logical operations to turbine function and safety.

Circuit Functionality

• At its core, the card contains a basic logic circuit composed of one "OR" logic element that is controlled or gated by two "AND" gates. The operation can be summarized as follows:
• If either of the two AND gates receives all input signals as logical “1”, the output of the OR gate—called CUT—will be a logical “1.”
• The card also includes an OR-E expander input, designed for use with another logic module known as the LLXA. This expander allows integration with additional logical circuits to build more complex control functions.

Outputs and Relay Drivers

• Each SLEH card provides three independent circuits, and each circuit features a relay driver output. These relay drivers act as electrical switches:
• When the output signal is a logical 1, the relay driver closes a contact to common, effectively energizing external relays or devices.
• This functionality enables the card to directly control external turbine components based on its logical conditions.

Input Signal Characteristics

The SLEH card is designed to work with high-level input signals compatible with GE's control system standards:

• A logical 0 is defined as a voltage up to 1.5 volts maximum.
• A logical 1 is defined as a voltage 4.75 volts minimum.
• This voltage range allows the SLEH card to directly interface with LGXA expander gates on its normal inputs without the need for additional signal conditioning.

FREQUENTLY ASKED QUESTIONS

What is GE Fanuc IC3600SLEH1F?
It is a Logic Element Card used in gas turbine control systems.

What kind of logic does the card implement?
The card implements a circuit with one OR gate gated by two AND gates. If either AND gate input is all logical 1, the output is a logical 1.

What does the relay driver output do?
The relay driver output closes a contact to common when the output signal is logical “1,” enabling control of external relays or devices.

What input voltage levels does the card accept?
Logical 0 inputs are up to 1.5 volts maximum, and logical 1 inputs are at least 4.75 volts, compatible with LGXA expander gates.
