BD120 Dual Level Trip Amplifier

Function: Dual Level Trip Amplifier from a mA or Voltage input. The operation of the trip relays can be arranged so that the Alarm condition for each relay can be either above (High Trip) or below (Low Trip) its set point, and that the relays can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).
