Note 1 - The input ranges, indication, relay usage as alarms and the alarm points
are, among other things, items that the user can program through the front keys (if
wanted, specify this information so that all the configuration can be made by PRESYS).
Note 2 - Other hardware and software features are available under previous
consult.
Code Example:
1) DMY - 2030 - F - 0 - 0 - 1 - 1 - 1 - 0 - 0
This code defines a DMY-2030-F Indicator with two SPDT relays which can be
used as high and low alarms, 90 to 240 Vac or 130 to 340 Vdc electric power supply,
protected field usage.
