Inquiry of External Switching Contacts and Control Voltages
The inputs can be used to interrogate external switching contacts with internal or external voltage. External control voltages can also be queried.
Provides Two Internal Power Sources
The board has two power sources that are galvanically isolated from the NEXUS system. One voltage can be used for external contacts, the other for the outputs. For smaller loads the output power of 5V/20mA is sufficient.
Combination of Two Contacts to One Potential-Free Contact
When two contacts are combined, a potential-free contact can be created. The second contact loses its function because its line is used for the ground.
Interface to Nexus Logic
The XRI is predestined to be integrated into the extensive NEXUS logic to query switching contacts or output control voltages.
Configuring Inputs and Outputs
In addition to configuring the floating contacts, the inputs and outputs of the XRI can also be assigned a voltage whose polarity can be changed.
Control with DC and AC Voltages Possible
Both DC and AC voltage can be used for control. A maximum permissible current of 1A or 4A peak current is possible at a voltage of up to 60V.
All Inputs and Outputs Equipped with Filters
To avoid the effects of interference such as noisy signals or crosstalk, both inputs and outputs are equipped with filters whose time constant is adapted to the requirements of the software.
