Hawkeye 720 Current Switch

Hawkeye 720 current switche are used for monitoring devices and provides unique solutions for accurately monitoring status of motors controlled by variable frequency drives.

Overview

Hawkeye 720 current switches are a part of Honeywell and are used as monitoring devices to provide unique solutions for accurately monitoring status of motors controlled by variable frequency drives. The microprocessor-based H904 and H934 store the sensed amperage values for normal operation at various frequency ranges in non-volatile memory. This information allows the device to distinguish between a reduced amp draw due to normal changes in the frequency and an abnormal amp drop due to belt loss or other mechanical failures. The relay on the H934 is isolated from the current switch, and all relay connections are externally accessible on the device. The H720 analog output corresponds to current in the monitored conductor from 10 to 80 Hz.
