Single-phase Voltage Relay
K8AB-VS
Ideal for voltage monitoring for industrial
facilities and equipment.
• Monitor for overvoltages or undervoltages.
• Manual resetting and automatically resetting supported by one
Relay.
• One SPDT output relay, 6 A at 250 VAC (resistive load).
• Output relay can be switched between normally open and
normally closed.
• Process control signal (0 to 10 V) and current splitter input
supported.
• Output status can be monitored using LED indicator.
• Input frequency of 40 to 500 Hz supported.
• Inputs are isolated from the power supply.
Refer to Safety Precautions for the K8AB
Series. Refer to page 9 for the Q&A section.

■ Shunts (Order Separately)
A shunt is a resistor to convert a DC current into a DC voltage.
Use the shunt in combination with K8AB-VS to detect undercurrent and overcurrent in DC circuits.

Note: 1. All the above listed shunts have an accuracy in the 1.0 class.
2. Select a shunt whose rated current is more than 120% of the
current normally flowing in a circuit. The characteristics of the
shunt may change or fusing of a resistor element may occur if an
overload that is 1,000% of the rated current is applied. Therefore,
determine the rated current of the shunt to be used, by taking the
circuit conditions into account.
