The Optional Alarm Module provides ok, alert and danger relays, selectable time delay, trip multiply, bypass and 0 to 5 VDC outputs for displays. The relay outputs can be used to trigger machine shut-down or other alarms. Combining transmitters with an existing PLC or DCS system results in a high density, low cost vibration monitoring system. Alarms relays and trip multiply are available with the Monitor version. Alarms – The CMCP500A Series Monitors have two independent set points, with LED alarm indicators and output relay contacts (Alert and Danger). Set points are adjustable via potentiometer, from 0 to 110% of full scale. Each has an adjustable delay of 1 to 10 seconds. SPST Relay contacts are rated 5 Amps @ 30 Vdc or 250 Vac for resistive loads. Relay contacts can be independently configured by the user for either Normally Open (NO) (Standard) or Normally Closed (NC) operation. Relays are normally de-energized and can be configured for latching or non-latching (standard) operation. Latched alarms may be reset locally or by remote contact closure. Trip Multiply – The monitors have set point multiplication of 3X via contact closure (2X available). To avoid tripping the alarms during machine start-up.

Custom Input and Output Calibrations are Available on Request.

For applications that require monitoring specific frequency bands, optional high-pass and low-pass filters can be specified. These filters are modular and can be installed by the factory or in the field. Each module attenuates out-of-band signals at a rate of approximately 24 dB/octave. Corner frequencies from 2 Hz to 20 kHz may be specified. Filter modules may be cascaded to form higher order filters or to create a band-pass response. Filtering does not effect the buffered transducer output.
