Digital Inputs
The digital inputs can be used for sensing of multiple dry contact digital inputs in applications, such as equipment status monitoring or alarm point monitoring.
As counter inputs, digital inputs are commonly used in energy metering applications.
Inputs
The DI digital inputs are designed to read two different types of inputs:
Digital
Counter
Digital inputs
The external connection of a digital input is shown in the following figure.
Figure :
Digital input external connection
K is the monitored external switch.
V S = 24 V
R PU = 10 kohm
Counter inputs
A counter input uses the same hardware configuration as the digital input that is shown in the figure above.
