AO MODULE

HIGHLIGHTS

  • 4x analog outputs
  • 1-5 Vdc (3-Wire) / 4-20 mA (2-Wire)
  • Designed for use w/ DH1 Wireless Gateway
  • RS485 serial / multi-droppable
  • -40 °C to 80 °C
  • Class I, Division 2 (Zone 2)

4x Analog Outputs

The OleumTech® Analog Output Module is designed for conveniently implementing up to four analog outputs to the DH1 Base Unit Wireless Gateway. Each output can be independently selected for either 1-5 Vdc (3-wire) or 4-20 mA (2-wire) mode of operation.

Low-Power, Small Footprint

The Analog Output Module is certified for use in Class I, Division 2 (Zone 2) hazardous locations and accepts 9-24 Vdc external power. Its compact, small footprint form factor easily fits inside a NEMA enclosure. This Module is equipped with two RS485 Serial ports (RJ-45) for allowing multiple I/O Modules to be daisy-chained to the DH1.
