Repeater Power Supply DC 52100

Powering and Isolation of 2- and 3-wire Transmitters

The repeater power supply DC 52100 is used to supply and separate 2- and 3-wire transmitters and active sensor signals.

  • Universal operation of Transmitters
    Energization and separation of field located 2-, 3- and 4-wire transmitters with current or voltage output
  • Calibrated signal setting
    Input and output range can be set by using DIP switch – high precision without any further adjustment
  • 3-Port isolation
    Protection against erroneous measurements due to parasitic voltages or ground loops
  • Extremely slim design
    6.2 mm slim housing for a simple and space saving DIN rail mounting
  • Optional In-Rail-Bus mounting rail connector
    allows for fast and economical installation
  • Protective Separation acc. to EN 61140
    Protects service personnel and downstream devices against impermissibly high voltage
  • 5 Years Warranty
    Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant (carriage and insurance paid by sender)

The repeater power supply supplies the transmitter with power and transmits the current or voltage measuring signal with high accuracy galvanic isolated to the output. Alternative the measuring input accepts active signals from 4-wire transmitters.

The input and output range of DC 52100 can be easily set by using DIP switch. Due to the calibrated range selection no further adjustment is necessary.

The auxiliary power can be supplied via the connection terminals or via the optional In- Rail-Bus connector. A green LED on the front of the unit has been provided to monitor the power supply.
