12.4 Active signal outputs, digital
Signals are routed to a superordinate controller via the
digital signal output "3.1 SIG".
The 24 V DC signal is applied between the connection
terminal blocks "3.1 SIG" and "2.2 -" or 2.3 -". The maximum
load is 30 mA.

IEC 61850-3 Immunity Requirement
Signal connections must satisfy the immunity requirement.
Equipment that is installed in "protected" areas and has
direct connections to other areas must satisfy the immunity
criteria.
Use Phoenix Contact surge protection (Order No. 2905223)
when you are using signal connection types p, l, f, and h for
the signal paths.
