The SELCO M3000 is a compact 24 channel Analogue Alarm Annunciator. The M3000 is ideal for surveillance of temperature sensors, pressure sensors and any other kind of sensors providing a signal within the range of 0-20mA, 0-10VDC or 0-30VDC.

A linearly pre-scaling is done in order to convert the measured input voltage or current into the entity measured by the sensor (e.g. temperature or pressure). Once this conversion has taken place, all further references are made to the measured entity.

Alarm Blocking is an integral feature of this product and can be activated on separate inputs.  See post about Alarm Blocking.
