The IFMR signal conditioner accepts frequency inputs, and controls a single relay (SPDT) based on the value of the input frequency. The relay can be set to trip based on any input 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 false outputs. Two separate input connections are available for external push-buttons are provided and override to the relay trip detection. This override holds the relay in the release state as long as the input is connected. The other external input clears a latched trip condition when pulled.
The IFMR signal conditioners can be easily configured using a seven position DIP switch, rotary switch and/or push-button. The input circuitry is also DIP switch selectable for a variety of sources.
The IFMR operates in one of six user selectable output modes. The programmable minimum response time provides optimum response versus input filtering for any input frequency. The offset and hysteresis settings provide flexible adjustment of the relay trip and release points.
LED lights on the face of the unit are illuminated during normal operation to display the input and output status of the IFMA. These LEDs are also used to provide visual feedback during device configuration. The unit is equipped with a universal mounting foot and can be mounted to either a top hat (EN 50 022) or a G profile (EN 50 035 – G32) DIN rail.
