parameters
Operational voltage:
– for E20-10
of revisions А and B
+9.0...+27 V
(when initiation voltage shall be within the range of
+9.5…+27 V, operational capability upon actuation is
within the range of +9.0...+27 V)
– for E20-10 of revision B.01 +8.0...+40 V
Power input (during operational voltage
supplying, with off-load output circuits of
E20-
10 ):
– for E20-10
of revision А
to 5 W
– for E20-10
of revisions В and B.01
to 4.5 W
Galvanic isolation from other circuits of E20-10 No

actual situation: sometimes third-party supplies have network cards with power negative pole at connector central
contact; in cross-connection of such card to E20-10 the module will be operating but it will not operate from such card
