K8AK-VW3 Rơ le bảo vệ điện áp Omron

Ideal for Voltage Monitoring for Industrial Facilities and Equipment. Monitor for overcurrents and undercurrents simultaneously.

• Monitor for overvoltages and undervoltages simultaneously. Separate settings and outputs supported for overvoltages and undervoltages.

• Manual resetting and automatically resetting supported by one Relay.

• Pre-alarm Monitoring Mode.

• Two SPDT output relays, 5 A at 250 VAC (resistive load).

• 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.
