supply unit 802x - 1

supply unit Type 8020, 8021 This supply unit is allowed for the operation of 24 VDC sensors, such as vent- and flow-captors, with AC supply voltage. The supply unit contains a 24 VDC 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. Housing: Clamp housing for standard bar as per DIN 46277 and DIN EN 50022 for the installation in switch cabinets or similar. Supply Unit Variations: Type 8020 : 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 25 m/s. Type 8021 : For NPN-switching sensors. These units trigger the output relay directly from lhe switching output of the sensor.
