AER-D13 - Relay Station


Programmable relay station

The AER-D13 is a capable of measuring an analog input value from 0-10 VDC or 0-20 mA and convert it to a 3 relays output signal. The relays function can be set by jumper from combined to single switching mode or by parameter for binary mode. The detailed settings may be programmed by the use of an external display and configuration device called OPA-S.



  • Control of three fan speeds with one analog output
  • Control of up to three heating or cooling stages
  • Switching of up to 240 VAC - 10 A with a low power device
  • Setting any combination of relays based on an input signal




  • Controls three relays with one analog input
  • Up to 10 A - 240 VAC per relays
  • Signal LED for each relays
  • Status LED
  • Easy installation for cabinet mounting and DIN rail
  • 0/2...10 V or 0/4...20 mA input signals, selectable with jumpers
  • Free programmable switching points for each relays with common programmable hysteresis
  • Relays can be configured to work in combined or single mode by jumper or binary coded mode (set per parameter)
