Slim 22.5-mm Design Features Two SPDT
Relay Outputs
Provides individual over
voltage and under voltage settings and outputs
1-/3-phase Power Supply
Many customers require the individual upper and lower limit outputs that
are normally available only in larger 45-mm relays. For the first time
from any manufacturer, OMRON has achieved this and more in a slim-body
design measuring just 22.5 mm. These relays not only offer advantages such
as 3-phase power supply compatibility and a resistive load contact
capacity of 6 A at 250 VAC, but they also reduce panel production cost
because they use 50% less space than previous models.
Pre-alarm Monitoring Mode Provides
Advanced Warning (K8AB-VW Only)
In plants and other sites that operate 365 days a year, unexpected
shutdowns must be kept to an absolute minimum. OMRON addresses this with
the K8AB-VW featuring a two-level pre-alarm monitoring mode with
individual trip outputs and pre-alarm warning settings (H/HH alarm and
L/LL alarm). The K8AB-VW makes scheduled maintenance viable because the
pre-alarm monitoring mode provides advance warning of impending trip
alarms.
Expanded Setting Range Ensures Over
Voltage and Under Voltage Monitoring Flexibility
The highly restrictive voltage settings that
posed such a problem in the past are no longer a concern. OMRON's new
Relays offer full-span over voltage and under voltage range settings for
unprecedented voltage monitoring flexibility.
Single K8AB Monitors 3-phase Power
Supply with 3 or 4 Wires
OMRON Low-voltage Monitoring Relays can be
used to monitor 3-phase power supplies with 3 or 4 wires simply by
changing DIP switch settings.
Operation Level Indication by
Flashing Alarm Indicator
 
Checking the operating status has never been
convenient because of the time it takes to reach the preset operation
time. The K8AB eliminates this problem by featuring a flashing alarm
indicator that clearly indicates the operating status. This has greatly
simplified the task of checking on-site status particularly when operation
settings are changed or an error occurs.
