Products - Coupler Units KR And KV
Special couplers and power controllers matched to the requirements of the different applications are used to provide a system-compatible interface between the automation unit and the power or switchgear section.
The coupler units available provide electrical isolation between the control and load circuits and amplify the signals coming from the electronic automation units.
The load circuits of devices intended for direct switching of solenoid valves are protected separately.
Some coupler models are capable of detecting power failures in the load circuit and of providing an electrically isolated error signal to the monitoring logics.
Depending on the coupler model, it is possible for the load circuit to be monitored for interrupts (wire break) and short circuits, resulting in the output of an error signal.
Important command and error signals are indicated by LEDs.
On some coupler models, the commands to the actuator devices can be simulated by means of a test probe.
The components of the couplers are mounted in robust plastic enclosures. These enclosures comply with protection class IP 40 (terminals IP 20) and are suitable for installation on standard rails (DIN EN 50 022, 35 mm width).
