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.
