All digital inputs/outputs are configurable using the DSE 890 (Drive System Explorer) Configuration Tool
supplied on disk. The table shows the factory defaults. The digital inputs require 24V DC which is supplied
at terminal X14/03. For further information refer to the DSE 890 Configuration Tool.
Relay outputs are volt-free, normally open contacts. Rated to 240V 3A resistive load. Alternatively they
may be used down to 1mA, 12V levels.
