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.

12.4.1 Signal level surge protection

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.

DIN EN 61000-6-5 Electromagnetic Compatibility

(EMC)

The interface area may include items such as equipment,

devices, apparatus, and systems connected to the outside

world.

Use Phoenix Contact surge protection (Order No. 2905223)

when you are using connection terminal blocks "3.1 SIG"

and "2.2 -" or "2.3 -" for the signals.

(see Section: Technical data, electromagnetic compatibility

table)
