Product Description Ordering Key
DIC01 and PIC01 are precise
TRMS AC/DC over+under,
over+over or under+under
current and voltage (selectable by DIP-switch) monitoring relays. DIC01 can perform also DC plus/minus
measurement by short circuiting pins Z3 and Y1. The
devices can be connected to
the MI or MP and A82 or E82
current transformers.
Both relays have two individual set levels with their own
time delay. Only for DIC01
each set level can work with
a single SPDT relay.
Owing to the built-in latch
function, the ON-position of
the relay output can be
maintained. Inhibit function
can be used to avoid relay
operation when not desired
(maintenance, transitions).
The LED's indicate the state
of the alarm and the output
relays.

Mode of Operation (cont.)
PIC01: The relay operates
when the voltage drops below
he under voltage set level
t
for more than the respective
et delay time or when it
s
exceeds the over voltage set
evel for more than the rela-
l
tive set delay time. The relay
releases when the voltage
exceeds the under voltage
set level plus hysteresis and
t drops below the over volt-
i
age set level minus hystere-
is (the hysteresis is the
s
same for both set levels).
Example 2
(latch enable active - under+under
current - 2 x SPDT relays (1 x
SPDT for PIC01) - TRMS)
DIC01: Each relay operates
and latches when the cur
drops below the respective
set level for more than the respective delay time. Provided
that the current has exceeded
the respective set level plus
hysteresis, each relay releas-
es when the contact input’s
connection is interrupted.
IC01:The relay operates
P
when the current drops
elow the higher set level for
b
more than the respective
elay time. Provided that the
d
current has exceeded the
higher set level plus hysteresis the relay releases when
the contact input’s connec-
ions is interrupted.

N
Different delay times can be
used for appropriate reaction
according to the set points.
Example 3
(inhibit enable active - over+over
current with MI CT - DPDT
rent
elay (SPDT for PIC01) - TRMS)
r
Provided that the contact
input’s connection is interrupted, the relay operates
when the current flowing in
the MI CT exceeds the lower
set level for more than the
respective delay time. It
releases when the current
rops below the lower set
d
level minus hysteresis or
hen the contact input’s
w
pins are connected.
Example 4
(inhibit enable active - over+over
current with A82-10 CT DPDT relay (1 x SPDT for
IC01) - TRMS
P
Provided that the contact
nput’s connection is inter-
i
rupted, the relay operates
when the current flowing in
the A82-10 CT exceeds the
lower set level for more than
its delay time. It releases
when the current drops
below the lower set level
minus hyster
contact input’s pins are connected.
Example 5 (DIC01 only)
(no contact input - under+over
voltage - 2 x SPDT N.D. relays
esis or when the
- plus/minus DC
One relay operates when the
oltage drops below the
v
under voltage set point for
ore than the respective
m
delay time. It releases when
he voltage exceeds the set
t
level plus the set hysteresis.
The other relay operates
when the voltage exceeds
the over voltage set point for
ore than the respective
m
delay time. It releases when
he voltage drops below the
t
set level minus hysteresis.
In this case the spare front
label has to be placed on the
device for proper level
adjustment.
Note
When the inhibit contact is
opened, if the input signal is
already in alarm position, the
delay time needs to elapse
before relay(s) activation.
