MODEL IFMR - DIN-RAIL SPEED SWITCH
DESCRIPTION
The Model IFMR accepts a frequency input, and controls a single relay
(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
