Definitions:

Discrete I/O Modules

Electronic devices used in automation systems to process binary signals from sensors (inputs) and to control actuators (outputs).

Analog Inputs

Inputs to a system that can represent a continuous range of values, unlike digital inputs which represent only distinct on or off states.

Leakage Current

The unwanted flow of electrical current through an unintended path, typically small in magnitude.

Surge Current

The temporary, rapid increase in electric current that occurs when power is first applied to a circuit or when there is a short circuit, potentially damaging components.
