Example 1
DC voltage metering
(AC power supply)
The relay operates when the
actual voltage reaches set
point.
The relay releases when the
voltage drops min. 10% be-
low set point (see hysteresis)
or when power supply is in-
terrupted.
Example 2
DC voltage metering -
latching (AC power supply)
The relay operates and re-
mains in operating position
when the actual voltage
reaches set point.
Provided that the voltage has
dropped min. 10% below the
set point (see hysteresis) the
relay will release when the in-
terconnection between pins 8
and 9 is interrupted. The relay
also releases when power
supply is interrupted.
Example 3
AC or DC metering
(DC power supply)
Please note that pins 7 and
10 are internally connected at
DC power supply. No current
must pass through this inter-
nal connection.
Mode of Operation
SJ 185
The SJ 185 measures the ave-
rage of a sinusoidal voltage
(input). The set point, cali-
brated to rms-value, is set on
built-in potentiometer.
Example 1
AC voltage metering
(AC power supply
The relay operates when the
voltage reaches set point.
The relay releases again when
the voltage has dropped min.
10% below the set point (see
hysteresis), or when power
supply is interrupted.
Example 2
AC voltage metering -
latching
(AC Power supply)
The relay operates and re-
mains in operating position
when the voltage reaches set
point.
Provided that the voltage has
dropped min. 10% below set
point (see hysteresis) the re-
lay releases when the inter-
connection between pins 8
and 9 is interrupted. The relay
also releases when power
supply is interupted.
Example 3
AC or DC metering
(DC power supply)
Please note that pins 7 and
10 are internally connected at
DC power supply. No current
must pass through this inter-
nal connection.
