| Supply Units Type 8010, 8011, 8020, 8021 for AC Connections |
 |
GENERAL DESCRIPTION:
The supply units allow for the operation of 24 VDC sensors, such as vent- and flow-captors, with AC supply voltage. The supply unit contains a 24 V DC transformer rectifier and a switching circuit with output relay with potential-free single pole double throw switching contact. An integrated LED displays the actual switching situation.
Housing Variations:
Type 8010, 8011: Macrolon housing with PG screwing for sensor, supply and output connection for wall mounting. For application where an AC Connection is available.
Type 8020, 8021: 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 8010, 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 15 m/s
Type 8011, 8021: For NPN-switching sensors. These units trigger the output relay directly from the switching output of the sensor.
