DC/DC power supply 801x series

AC/DCsingle-outputswitching

This supply unit is allowed for the operation of 24 VDC sensors, such as vent- and flowcaptors, 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 Makrolon housing with PG glands for sensor, mains and output connection for wall mounting. For applications where an AC power source is available on site. Device variants Type 8010 : 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 to 25 m/s. Type 8011 : For NPN-switching sensors. With these devices, the output relay is controlled directly by the switching output of the sensor.
