B&R 3AO360.60-1

Model Series: X20 System (AO = Analog Module — Output)

Product Overview:
The 3AO360.60-1 is a 2-channel analog output module from B&R’s X20 I/O system. It generates analog control signals (current or voltage) to drive field actuators such as control valves, variable frequency drives (VFDs), and proportional controllers. The module features 12-bit resolution and supports both 4–20 mA and 0–10 V output ranges.

Installation Requirements:

  • Mount on DIN rail TS 35 (7.5 mm module width)
  • Connect to X20 bus via RJ45 daisy-chain
  • 24 V DC power via X20 bus — no external power required
  • For 4–20 mA: connect actuator in series with module output (loop-powered)
