Although originally designed to monitor engine speed, these versatile units can be used with almost any rotating machinery. They are powered from either 12V or 24VDC. Separate frequency inputs are provided, one for 115/230V 50/60Hz and the other for connection to a Magnetic Pick-Up (or Tachometer). Three seperate speed trips are provided, each with it’s own threshold potentiometer, LED, relay and volt-free contact set. The MSM331 build has the addition of a delay-on-timer (T0) which times from the S1 trip level. This is typically used as a hold-off timer to allow egine parameters to stabilise prior to shutdown channels being enabled. Cased and customised versions are available to order.
