  • Digital Coupling Module KBD-1

    €20.00

    In building automation, as well as in process control, it is very practical to switch a relay contact on or off during commissioning and service. This means operating a valve, a pump, heating or ventilation in manual mode. With the switch feedback, the controller is informed whether the coupling module is in automatic or manual mode.

    The KBD-1 coupling module contains 1 circuit with 1 changeover contact for a load of 12 A / 250 V AC, which can be controlled with 24V AC/DC.

  • Digital Coupling Module KBD-1/L

    €26.33

    Switching on lights can lead to very high inrush

    current peaks.

    A closing contact can bounce 3 to 7 times until it has

    closed completely. This creates a light arc which can

    melt the contact surface. Micro-welding can take

    place when the contact cools down (contact sticks).

    To prevent sticking of the contact, relays with a

    preceding tungsten contact are used.

    Inrush current peaks for filament lamps of 165 A /

    max. 20 ms, or for fluorescent lamps of 800 A / max.

    200 µs can be switched with these.

  • Digital Coupling Module KBD-1/M

    €20.00

    • 1 switching circuit with 12 A The switching circuit is capable of switching an output of 12 A /250 V AC. • Minus activation For the new generation of controllers with minus outputs, the A3 activation is activatable with a minus.

    • AUTO-OFF-ON with feedback The switching circuit can switch to automatic or manual mode. In automatic mode the contact with feedback is closed, therefore a logic 1 results on the controller. Multiple feedbacks can be connected in series.

    • DIN 45 mm housing The standardised housing enables the KBD-1 to be installed by means of a 45 mm cut-out behind the covering, it only requires a width of 17.5 mm for this. It only requires a width of 17.5 mm.

  • Digital Coupling Module KBD-2

    €35.32

    In building automation, as well as in process control, it is very practical to switch a relay contact on or off during commissioning and service. This means operating a valve, a pump, heating or ventilation in manual mode. With the switch feedback, the controller is informed whether the coupling module is in automatic or manual mode.

    The KBD-2 coupling module contains 2 circuits, each with 1 changeover contact for a load of 12 A / 250 V AC, which can be controlled with 24V AC/DC.  

  • Digital Coupling Module KBD-2/L

    €48.16

    Switching on lighting fixtures can result in very high inrush currents. A closing contact bounces 3-7 times until it closes completely. This creates an arc that can melt the contact surface. If the closed contact cools down, micro-welding can occur (contact sticks).

    To avoid contact sticking, relays with a leading tungsten contact are used.

    This allows switch-on peaks of 165 A / max. 20 ms for incandescent lamps, or 800 A / max. 200 µs for fluorescent lamps.  

    An 8-pole connection comb is available for faster wiring of the supply A1 – A2.

  • Digital Coupling Module KBD-2/M

    €35.32

    • 2 independent circuits with 12 A

    Every separately controllable switching circuit is

    capable of switching an output of 12 A / 250 V AC.

    • Minus activation

    For the new generation of controllers with minus

    outputs, the A3 and A4 activations are activatable

    with a minus.

    • AUTO-OFF-ON with feedback

    The switching circuit can switch to automatic or

    manual mode. In automatic mode the contact with

    feedback is closed, therefore a logic 1 results on

    the controller. Multiple feedbacks can be connected in series.

    • DIN 45 mm housing

    The standardised housing enables the coupling

    module to be installed by means of a 45 mm cutout behind the covering, it only requires a width of

    17.5 mm (8.75 mm per channel) for this.

  • Digital watchdog WDR-2

    €62.39

    2-channel digital watchdog coupling module with predefined switching action in the event of a controller failure.

  • DIN relay coupler DRK-1/L

    €21.65

    Switching on lighting fixtures can result in very high inrush currents. A closing contact bounces 3-7 times until it closes completely. This creates an arc that can melt the contact surface. If the closed contact cools down, micro-welding can occur (contact sticks).

    To avoid contact sticking, relays with a leading tungsten contact are used.

    This allows switch-on peaks of 165 A / max. 20 ms for incandescent lamps, or 800 A / max. 200 µs for fluorescent lamps. 

    An 8-pin connection comb is available for quick wiring of the negative pole A2.
