6.3.4 USR1 and USR2 relays
The USR1 and USR2 relays are available in free voltage contacts or as supervised outputs.
Contact range: max 30 V AC / DC, 2 A, Non-inductive loads Selection of type of contact
(Normally open, normally closed or supervised outputs) refer to Chapter 4.4.2.
To program the activation of these outputs refer to MA-2000 Commissioning Manual.
