Coupling modules

• Analogue manual mode

The coupling module can be switched over to manual mode. This allows an analogue signal of 0 - 10 V

or 0 - 20 mA to be generated independently of a

controller.

• AUTO-OFF-ON with feedback

The coupling mode 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 for this.

• Analogue manual or emergency operation

The coupling module can switch to manual or

watchdog mode. This allows an analogue signal of

0 - 10 V to be generated independently of a

controller.

• 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 for this. 

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.

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.

• 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.

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.  

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.

• 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.

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

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.
