Timer relays

  • THBBU 400 relay – Priority, delay on pull-in

    The THBBU 400 is a pull-in and drop-out relay which can be directly pull-in by “0V” on d3 pin. This command is priority on relay pull-in. It is equipped with 4 double make / double break C/O contacts (form Z). The relay is fully programmable with a dip switch for time setting. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time…
  • TPBAU 400 relay – One-shot time delay

    The TPBAU 400 is a one-shot on pull-in or drop-out relay with 4 double make / double break C/O contacts (form Z). The delay is triggered by the up front of the command input and is fully programmable with a dip switch from 0.25 s to 63 min. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time delay setting. The plug-in…
  • TPBAUN 400 relay – One-shot time delay with negative edge command

    The TPBAUN 400 is a one-shot on pull-in or drop-out relay with 4 double make / double break C/O contacts (form Z). The delay is triggered by the negative edge of the command input and is fully programmable with a dip switch from 0.25 s to 63 min. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time delay setting. The plug-in…
  • TPBBU 400 relay – One-shot time

    The TPBBU 400 is one-shot time on pull-in or drop-out relay with 4 double make / double break C/O contacts (form Z). The delay is triggered by the up front of the command input and is fully programmable with a dip switch from 0.25 s to 63 min. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time delay setting. The plug-in…
  • WDB4-U200N One-shot Timer Relay with ON Delay

    Plug-in electronic railway one-shot timer relay with time delay on pull-in, three change-over contacts and one normally-closed contact for reliable switching of very low currents (1 mA @5 VDC) up to currents of 10A @ 110VDC. Application The WDB4-U200N is used in applications where one pulse at output is necessary after activating the relay (with or without time delay). Features Auxiliary power supply necessary Compact plug-in design 3 C/O contacts…
  • WDE4-U200N relay – Timer, one-shot, 4 pole

    Plug-in electronic railway timer relay with four change-over contacts for reliable switching of very low currents (1 mA @ 5 VDC) up to currents of 10A @ 110VDC. When the relay is activated, the coil is energized with one pulse. The pulse time is adjustable with a lockable knob. The relay can also be supplied with a fixed pulse time (no knob). The relay is equipped with two LEDs which…
