VFD Compatible Current Switch with Integral Command Relay, N.O., Solid-State 0.1 Amp @ 30VAC/DC, Status LED, Relay Power LED, Detects belt loss - The Hawkeye 934 microprocessor based current status switch with integral command relay provides a unique solution for monitoring status and starting/stopping motors controlled by variable frequency drives. To provide accurate status on loads controlled by Variable Frequency Drives (VFD), the H934 stores the sensed amperage values for normal operation at various frequency ranges in nonvolatile memory. This information allows it to distinguish between a reduced amp draw due to normal changes in the frequency and abnormal amperage drop due to belt loss or other mechanical failures.
