KDW2ext

Condensation Switch – KDW2Ext The KDW2Ext condensation switch has the advantage that, thanks to the remote measuring point, it can also be used very easily in hard-to-reach places. This means our condensation switches can be used as monitors on cooling ceilings or pipes, and an additional switching output within the device can reliably activate a heater or other actuators.

Technical Data

Switching point Sensor system: Adjustable between 80 and 100% Switching hysteresis: approx. 5% RH Operating range: 0…100% RH Operating temperature: -30°C…+70°C Condensation: permitted Condensate: permitted for short periods Measuring Medium: ambient air without additives Response time: approx. 120 sec With a step change from 75% RH to condensation Cable length with KDWext: 2000mm silicone Power supply Operating voltage: 15…36VDC or 24VAC Operating current (at 24V DC): Relay energized 30mA max. Relay de-energized 15mA max. Potential-free relay with changeover contact, energized in normal operation (condensation-free). If there is no operating voltage, the relay is de-energized; if there is condensation, the contact voltage is also: max. 60 Vpp switching current: max. 1 A AC/DC switching display: LED green (energized) LED red (relay de-energized) Switching capacity relay: 60V/1A
