MODEL IFMR - DIN-RAIL SPEED SWITCH
DESCRIPTION
(SPDT) based on the value of the input frequency. The Trip frequency can be
set to any value from 0.1 Hz to 25 KHz. The IFMR can be set to trip on
overspeed, or underspeed (including zero speed). Offset and hysteresis values
can be incorporated into the trip setting to eliminate output chatter. LED
indicators for both the Input signal and the Relay status are provided. Two
separate input connections for external push-buttons are also provided. One
external input overrides the trip detection function, and holds the relay in the
release state as long as the input is pulled to common. The other external input
clears a latched trip condition when pulled to common.

operational parameter set-up, input signal, and relay status indication. The input
circuitry is DIP switch selectable for a variety of sources.

feedback to the user of the current parameter settings during parameter set-up.
