Weber Sensors 8020 Power Supply Units for Flow and Vent Captor Products 110VAC for PNP Switching Sensors

The supply units allow for the operation of sensors, such as vent- and flow-captors, with AC supply voltage. Tue supply unit contains a transformer rectifier and a switching circuit with output relay with potential free single pole double throw switching contact. An integrated LED plays the actual switching situation.

For PNP-switching sensors or sensors with analog output signal. On connection of an analog signal to the input of the Supply Unit a switch Signal is activated which controls an integrated relay when a fixed threshold of 50% of the max. input signal is reached. This provides the possibility, when connecting flow and vent-captors with adjustable measuring range, to vary the switching point on a large scale; e.g. for the flow-captor 4114.30 related to water at Flow velocity between 10 cm/s and 100 cm/s, resp. for the vent captor 3202.30 related to air between 50 cm/s and 15 m/s.
