The EL2872 digital output terminal offers a very compact design with its 16 channels. A 20-pin contact strip enables the secure connection of plug connectors using insulation displacement contact, as is usual for ribbon cables and special round cables. This significantly simplifies the wiring of many channels. The signal states of the channels are indicated by LEDs.

 

Special features:

  • Connection of different load types possible (ohmic, inductive, lamp load)
  • Ideal for valve terminals with multi-pin plug connection
  • Max. output current 0.5 A per channel
  • Short-circuit-proof outputs and reverse polarity protection
  • Direct connection of connectors with insulation displacement contacts
