  • UMD-U200 relay – Voltage monitoring

     This product is no longer available. The replacement relay is the MTDV4-U200. Plug-in electronic voltage monitoring relay with one change-over contact and one normally open contact. The pull-in voltage is adjustable with a lockable knob. The relay can also be supplied with a fixed pull-in voltage (no knob). The UMD-U200 offers a very small hysteresis (difference between pull-in and drop-out voltage) and does not need an auxiliary supply. The relay…

  • UMD-U300 relay – Voltage monitoring, AC input

     Plug-in electronic voltage monitoring relay with one change-over contact and one normally open contact, suitable for AC voltages with a frequency of 50/60 Hz. The pull-in voltage is adjustable with a lockable knob. The relay can also be supplied with a fixed pull-in voltage (no knob). The UMD-U300 offers a very small hysteresis (difference between pull-in and drop-out voltage) and does not need an auxiliary supply. The relay is equipped…

  • UTC relay – Voltage monitoring & off delay

     The time delay relay UTC incorporates also a voltage control function. The time delay is initiated by an impulse on the relay command which also closes the contact. The time delay relay can be initiated if the input voltage d0 is higher than the voltage control threshold. If the input voltage d0 is lower than the voltage control threshold, then the time delay is reset to 0, the contact is…
