Industrial plug-in power relays

  • DI series, current monitoring, power relays

     D-I series, 2 C/O, 10A (more…)

  • EA 111 relay socket

     The EA 111 is a relay socket for all A/B platform relays, with two highly reliable spring clamp terminals per socket. The socket can be mounted on a surface/wall and 35 mm rail. Hexagonal plastic keys and round plastic plugs are provided for relay type coding, not inserted. Keying can be provided as an option. (more…)

  • FDA series, interval timer relay (flashing relay)

     Plug-in electronic pulsing relay with two change-over contacts, suitable for DC and AC coil voltage (50/60 Hz). When the relay is activated the coil starts with an interval. The pulse time and interval time are equal. The pulsing frequency is adjustable with a lockable knob. The relay can also be supplied with a fixed pulsing frequency (no knob). The relay is standard equipped with double zener diode coil protection. The…

  • FDA4 series, interval timer relay (flashing relay)

     FDA4, interval timer relay, 4 C/O, 10A Interval timer relay (flashing relay) for heavy duty, demanding applications, switching of AC & DC voltages, resistive and/or inductive loads. Pulse = interval time. Start with intervaltime 20...60 flashes/minute, 40...120 flashes/minute Plug in power relay Smitt-style pining 4 C/O contacts DC and AC coil Flash barriers LED indicator Cadmium free contacts Adjustable with a lockable knob Integrated 'snap-lock' retaining clip This relay is obsolete from January 1,…

  • FDC series, interval timer relay (flashing relay)

     FDC, interval timer relay, 2 C/O, 6A (more…)

  • KCD series, latching relay (bistable), magnetic latch

     KCD relays, latching, 2 C/O, 6A (more…)

  • KCS series, latching relay (bistable), magnetic latch

     KCS relays, latching, 2 C/O, 6A (more…)

  • KDN series, latching relay (bistable), mechanical latch

  • KDN-R8, Industrial latching fast trip relay, 8 pole

     KDN relays, latching, 8 C/O, 10A The KDN-R8 relay is a plug-in fast trip bistable tripping relay that features 8 changeover (C/O) contacts. The contacts of this relay remain in the last powered position, and the position is clearly shown to the user via a position- indicator. Latching (bistable) relay Magnetic arc blow-out for high breaking capacity Back EMF suppression diode on trip and reset inputs 8 C/O contacts Fast Tripping <10ms Wide…

  • Module 19-inch 2U D-relay

     The 19” module is equipped with 8 pieces of the V33 relay socket. Each contact on the V33 socket has two high-quality spring terminals, suitable for two wires up to 2.5mm2 (solid or stranded), the looping/daisy chaining can be done on the socket and no external connector or terminal is needed. The spring terminal makes the quick connection possible by pressing the spring with a flat-bladed screwdriver and inserting the…

  • MTDV4 relay – Voltage monitoring, timer delay-on -off, 4 pole

     Plug-in electronic voltage monitoring relay with optional delay-on and delay-off timer function and four change-over contacts. The delay time is adjustable with a lockable knob (either delay-on or delay-off, the other delay is fixed). The relay can also be supplied with fixed time delays (no knob). The pull-in voltage and drop-out voltage are both adjustable via internal screws. The relay can also be supplied with a fixed pull-in and drop-out…

  • TDB2 series, delay-on timer relay

     TDB2, delay on timer relay, 2 C/O, 6A (more…)

  • TDB4 series, delay-on timer relay

     TDB4, delay on timer relay, 4 C/O, 10A (more…)

  • TDBE4, dual function timer relay

     Plug-in industrial electronic timer relay with delay-on and delay-off function and three change-over contacts and one normally-closed contact. The delay times are independently adjustable with two lockable knobs. The relay can also be supplied with one or two fixed delay times (one knob or none). The relay needs an auxiliary supply and can be activated with an external N/O contact or with AC or DC supply voltage. (more…)

  • TDDB series, delay-on timer relay

     Delay off timer relay for demanding applications, switching of AC & DC, voltages, resistive and/or inductive loads. Plug in 2CO contacts direct and 2 C/O contacts time delayed DC and AC coil Flash barriers LED indicator Cadmium free contacts ‘Smitt-style’ pinning with integrated retaining clip silver plated Adjustable with a lockable knob This relay is obsolete from January 1, 2023.

  • TDE4N relay – Timer, delay-off, 4 pole

     Plug-in electronic industrial timer relay with four change-over contacts. When the relay is de energized there is a delay on drop-out without any auxiliary power supply. The delay time is adjustable with a lockable knob. The relay can also be supplied with a fixed time delay (no knob). The relay is equipped with a LED which indicates the presence of energizing voltage. Standard equipped with back EMF suppression. Optionally equipped…
