FEATURES
-
CRD-020 Programmable
ac current set-point relay setting for threshold levels,
over and under-current operation
-
CRD-005 Programmable
dc voltage set-point relay setting for threshold levels,
over and under-voltage operation
-
CRD-005
internal DIP-switches allow for either 0-1mAdc or 0-10Vdc
operation, and
may be set for under-alarm or over-alarm relay operation
-
CRD-020
internal DIP-switch
allow configuration of the ac current range to either 0-5A, 0-10A, 0-15A or 0-20A and the relay mode for under-current or over-current
operation
-
Lid mounted
two digit numerical push button switch calibrated as
percent of full scale with a threshold range of
1-99%
-
Red LED
lamp lights to indicate when the threshold level has
been tripped

indicates Factory Setting. The CRD-020 unit is shipped from the factory with
a 0-5Amp input and in an over-current relay mode. The set point
relay can be set to provide any one of the four current ranges
and modes of operation.
* The output relay will energize when
instrument power is applied and the current is above the set
point threshold. It will remain in a "Fail Safe" mode until
either the input current drops below the set point threshold or
instrument power is removed. |
** The output relay will energize when
instrument power is applied and will remain in a "Fail Safe"
mode until either the instrument power is removed or the
input current exceeds the set point threshold level.
