External operating voltage
Voltage selectable in order code (same as DI
threshold voltage for the relay):
A: 24 V dc / 110 V ac
B: 110 V dc / 220 V ac
C: 220 V dc
Operating voltage level

Terminal block
Phoenix MVSTBW or equivalent
Maximum wire dimension:
2.5 mm2 (13 – 14 awg)
NOTE! Approximately 2 mA of current is going trough the T5 (X6:1 & X6:2) circuit
even when used as a digital output. This has to be noticed when T5 is
used with certain type of applications (if 2 mA is enough to control for
example a breaker).
When DI/DO-option cards are ordered separately the threshold has to be
modified manually on field according the description in the manual (See
chapter 8.6).

Disturbance recorder (DR)
The operation of disturbance recorder depends on the following
settings. The recording time and the number of records depend
on the time setting and the number of selected channels.
