Digital Inputs
DOS Input ..............................
Dry contact, non-potential sensing or 4 V to

Figure 1: End of Line (EOL) Sensing Circuit
NOTE:
These Inputs can be individually configured to have End of Line (EOL)
Sensing in the Software via the Communications Protocol. With End of Line
Sensing active, the Input detects when the input line has gone open or
closed circuit. Connect a 1 kOhm Resistor either in series with, or in parallel
to, the Dry Contact, mounted as close as possible to the Dry Contact for
effective End of Line Sensing.
The recommended connection of the Resistor for Normally Closed (NC) and
Normally Open (NO) contacts is shown in Figure 1. For Normally Closed
Dry Contacts, connect the 1 kOhm Resistor in series with the contact; while
for Normally Open contacts connect the Resistor in parallel with the contact,
see Figure 1.
