Control Port Window: Digital Inputs

The Digital Inputs are high or low only. They are current driven and will accept +5V or +10V inputs (+25VDC max), and are well suited for sensing contact closure (Figure 5.6). They switch at approximately +1 VDC. They can be used to control one or more objects with the DBC Network Bridge. The Control Port digital inputs can be used to sense logic 'high' or 'low' signals to control many of the features of the DBC Network Bridge.

Find the Digital Inputs section (Figure 5.5) in the Control Port window. Its features are described below.
