Channel Value
When there is no load, the current type channel value =
range
÷
(-4), for example, when the range is 2 MPa,
the channel value is -0.250, and the voltage type
channel value = random value.
Note
If the equipment has three 5-PIN terminals, they are
three separated AI ports, which can connect with three
different sensors. But the AI interfaces are
standard-alone interfaces, cannot be extended by using
the external junction box. Different types of sensor
channels can be distinguished based on the labels.
2.4.3 DI/PI interface
DI/PI interface corresponds to 4PINS terminal and the definition is shown
