Analog input modules are used in applications where the. field device's signal is continuous. Unlike discrete signals, which possess only two states (ON. and OFF), analog signals have an infinite number of. states.
What are analog inputs in PLC?
What is analog input in PLC? The PLC's Analog Input Module (AIN) is a critical subsystem. AINs are used to condition physical parameters in the actual world, such as temperature, pressure, force, and strain. These AIN inputs are typically command signals in voltage (e.g. 10V) and current form (e.g. 4-20mA).
Why analog input 4/20mA?
There are two reasons. One reason is to avoid interference. Another reason is that the 4-20mA uses a two-wire system, that is, the two wires are the signal wire and the power wire at the same time, and 4mA is to provide the static working current of the circuit to the transmitter use.
