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.
2 circuits with 12 A
Each circuit can switch an output of 12 A / 250 V AC.
AUTO-OFF-ON with feedback
The circuits can be switched to automatic or manual operation. The contact of the feedback is closed in automatic mode, so that there is a logical 1 on the controller. Several feedbacks can be connected in series.
DIN 45 mm housing
With its standardized housing, the coupling module can be installed behind the cover with a 45 mm cut-out, taking up a width of only 17.5 mm. The switching status indicators (LEDs) are visible, the AUTO-OFF-ON switches are accessible, and the connections are protected behind the cover.
