4 and 8-Channel Analog Outputs, 0–20 mA

These 4- and 8-Channel Analog Output terminals generate signals in the range between 0 to 20 mA. Electrically isolated power is supplied to the process level with a resolution of 12 bits. The output stage is powered by the 24 V supply.

  • The 4-channel version uses 2-wire connections for all four outputs
  • The 8-channel version combines all eight channels in one housing, using single-wire connection technology that allows control of multiple actuators while minimizing space requirements inside the control cabinet
  • Power contacts are looped through, and the bus terminals have a common ground potential with the 0 V power contact
  • LEDs indicate the status of the data exchange with the bus coupler
