The relay is energized when the level falls below the low level
probe. It de-energizes when the high level probe is reached.
The NRU will also control a single level. In this case, a single
probe is used and the relay operates when the probe is not
immersed. The Max terminal is connected to common with a

The output relay energizes when the liquid level reaches the high
probe. The relay de-energizes when the liquid falls below the low
probe. This control can also be used with only two probes by connecting the maximum and common terminals together. The output is
energized when the level reaches the low probe. In both functions,
if the container is conductive, it may be used as the common probe
in some applications.

The electronic alternating relay is designed to replace mechanical
style devices used in control applications requiring a duplexing
or alternating action of the control circuits to operate pumps,
compressors, etc. This is achieved by activating a control switch
which is common to one side of the input control voltage. The output
contact of the relay(s) change state when this switch is opened
(on de-energization of the control circuit). When the control initiate
switch is actuated and released or opened, the relay will change
state. The next time the initiate switch is actuated and released it
will change back to its original state. Two red LED’s located on the
top of the dust resistant enclosure provide the status of the relay.

The output relay is energized when the current (peak current on AC) overshoots the level selected on the potentiometer. It de-energizes when the
current falls below the normal current by 5 to 50% or when input power
breaks. The hysteresis is controlled by a top mounted potentiometer and
its selection does not change the chosen current level.
2. AC Current Control With Latching:
The output relay is energized when the current reaches the selected value
and stays latched. The contact between terminal B1 and B2 (or 11 and 9)
should be opened or input power to the device interrupted to reset. In this
case, it is preferable to reduce the hysteresis 5%.

Note: Upon energization of the current control IR.T Series Relay,
the time delay, which is adjustable from .1 to 10 seconds, inhibits
the output relay during start-up periods. The delay time is adjustable
via a potentiometer located on the side of the case. Applies to both
versions, with and without latching.
Option: 24 VDC power - the voltage and the measured current must be
from separate sources.
Note: It is recommended that the unit be adequately fused.

The DIAR.T is a current control which is capable of sensing up to 100

has a 0.4˝ diameter center hole through which a current carrying lead
is routed. Automatic or manual unlatching is available in each unit.

The hysteresis is controlled by a potentiometer and its selection does

The output relay is energized when the voltage reaches the selected

The voltage threshold SR Relay controls a voltage supply which
is its own supply. The output relay is energized when the supply
(effective for AC) exceeds the selected threshold. It de-energizes
when the controlled supply falls below (5 to 20% Hysteresis) of
the supply voltage or when the input power breaks. Hysteresis
is controlled by a potentiometer and its selection does not
change the chosen threshold. Pulses or drops of 100ms or
