Functional Description

IC3600LLEA1C is a logic inverter circuit board developed by GE. It is a part of Mark I and II control systems. The logic inverter circuit board plays a vital role in these control systems, facilitating the efficient and precise control of various processes and machinery. By inverting logic signals, it ensures the correct operation of devices and machinery connected to the system, contributing to the overall reliability and safety of the controlled processes.

Features

• The LLEA, or Logic Inverter Circuit Board, serves a vital function in logical operations by implementing the NAND (NOT AND) operation. Each LLEA card is designed with a total of five circuits, identified as "A-E" and "OR-E" expander inputs. These inputs are intended for connection to LGXA and LLXA, respectively, in the larger control system. However, on each card, the remaining four circuits are configured as standard NAND gates.
• Now, when it comes to these NAND gates, a specific symbol is used to represent their operation, and the choice of symbol depends on the desired logic level at the output, which is used to signify the active condition of the inputs. This logic level, indicating the state of the inputs, is specified and defined through the output signal nomenclature.
• In the context of the active condition, which is typically denoted by an illuminated LED, the symbol mentioned earlier is employed to illustrate this state, and the output is designated as "X." The specific symbol used is a crucial determinant of the logic level in this active state, and it varies based on the circuit driven by the LLEA.
• Conversely, when the active condition involves the energization of relay X, a different symbol is used. In this case, if the desired representation at the "OUT" is "1" to indicate the active condition and the activation of the relay, the same symbol, as previously described, is used, and the output of the LLEA is correspondingly labeled as "X." The choice of symbol is directly linked to the desired logic level and its association with the operation of the relay.

FREQUENTLY ASKED QUESTIONS

What is IC3600LLEA1C?
It is a Logic Inverter Circiut Board developed by GE

How is the logic level specified for the active condition of the inputs?
The logic level for the active condition is specified and defined through the output signal nomenclature. This nomenclature provides a standardized way to indicate the state of the inputs.

What is the significance of an illuminated LED?
An illuminated LED is typically used to denote the active condition of inputs. When the LED is on, it signifies this state. The symbol mentioned earlier is used to represent this condition, and the output is labeled as X.

How does the choice of symbol relate to the operation of a relay in the LLEA system?
When the active condition involves the energization of a relay, a different symbol is used. If 1 is desired at the OUT to indicate the active condition and the activation of the relay, the same symbol, as previously described, is used, and the output is labeled X. The choice of symbol is directly tied to the desired logic level and its connection to the relay operation.
