    Shorted SCR Alarm The Watlow DIN-A-MITE alarm option provides an alarm output for shorted SCR conditions. A shorted SCR alarm is detected when there is no command signal and a load current is detected. The alarm output is then energized. This is a non-latching alarm.
  • Page 6 An external ElectroMagnetic Interference (EMI) filter must be used in conjunction with the DIN-A- MITE for loads in excess of six amperes (6A) at 150 to 250 KHz. Watlow has verified that a tank filter will suppress EMI created by SCR power controllers to comply with the conducted emissions limits.
