Chapter 4 Product function introduction
4.1 DO output mode
The output mode of the relay is output in different modes according to the mode set by the user, and the default level is
output.
4.1.1 Level output
Output according to the level set by the user. The switching characteristics of the level mode are similar to the function of
a self-locking switch.
4.1.2 Pulse output
After the pulse output is turned on, each time the DO output is controlled, the DO output will be automatically turned off
after the relay is closed to set the pulse width. The pulse width setting range is 50
～
65535ms (default 50ms).
4.1.3 Power-on state
According to the status set by the user. After the device is powered on, the output relay is turned on according to the state
set by the user, and it is turned off by default.
4.2 AI input mode
4.2.1 Analog range
Analog input AI measures the current signal, the acquisition range is 0-20mA or 4-20mA, the accuracy is 3‰, and the
resolution is 12 bits. Adopt single-ended input, sampling frequency 10Hz, input impedance 100Ω.
Set the sampling range of all AI channels, valid values are 1 and 0 (default 0).
Configured as 0: means 0
～
20mA
Configured as 1: Represents 4
～
20mA
[Note] Description of AI range configuration:
1. The AI sampling range is shared by all channels. When the AI channel sampling range is configured as 4-20mA
sampling, if the current signal is lower than 4mA, the engineering value of the channel is converted to 0. For signals
greater than 20mA, there is no conversion limit, but it should not exceed 25mA (exceeding 25mA may cause
equipment damage).
