Specifications are subject to change without notice (21.10.00)
3
Selection of measuring range:
DIP-switch selector (1 to 2)
12
2 to 20 V input range
5 to 50 V input range
20 to 200 V input range
50 to 500 V input range
Selection of function:
DIP-switch selector (3 to 6
and 1A, 2A)
3
Relay de-energized in
normal condition.
Relay energized in normal
condition.
4
Power ON delay 6 ± 0.5 s
Power ON delay 1 ± 0.5 s
5
Contact input as latch func-
tion enable. When the contact
is closed the latch function is
activated. The reset of the latch
condition occurs when the con-
tact is open or by power down.
Contact input as inhibit of
alarm enable. When the con-
tact is closed the relay remains
in normal position even if alarm
condition occurs
6
Set point 1 over voltage
monitoring relay. The alarm con-
dition occurs when voltage input
is over the set point value.
Set point 1 under voltage
monitoring relay. The alarm
condition occurs when voltage
input is under the set point
value.
1A
ON
Set point 2 over voltage
monitoring relay. The alarm
condition occurs when voltage
input is over the set point value.
Set point 2 under voltage
monitoring relay. The alarm
condition occurs when voltage
input is under the set point
value.
2A
2 x SPDT relays
(DUC01)
1 x DPDT relay
(DUC01)
Selection of level and time
delay:
Upper knob:
Setting of hysteresis on rela-
tive scale: 0 to 30% on set
value.
Centre knobs:
Current level setting on rela-
tive scale: 10 to 110% on full
scale.
Lower knobs:
Setting of delay on alarm time
on absolute scale (0.1 to 30 s).
