The EX series card-type I/O consists of an adapter module, an I/O module, a power supply module, and a terminal module.
The analog modules are divided into input and output modules, and according to the signal type, they are divided into voltage type and current type. According to the resolution, they are divided into 12-bit and 16-bit, and according to the number of channels, they can be divided into 4-channel and 8-channel.
Today, Xiaode will give you a detailed introduction to the appearance markings, channel indicator light definitions, and other features of the EX series analog modules.

2. Detailed Explanation of Channel Indicator Lights
Taking the above diagram as an example, there are four indicator lights on the top of the analog module, corresponding to the four channels.
The indicator light has three working states: flashing, constantly on, and off. The definitions of the three working states of the indicator light are as follows.
"Flickering" indicates that there is a signal, but the full scale is not yet available.
"Always on" indicates that the module has received a full-scale or over-scale signal.
"Extinguished" indicates that the sensor model is incompatible, the output signal is incompatible, or there is no signal.
