I/O Systems - SD Series I/OAO01

The AO01 Analog Output module processes up to 16 high level, group isolated, analog output field signals. Each channel is independently configurable for either 4 to 20 mA or 1 to +5 VDC ranges. FC 221 (I/O Device Definition) sets AO module operating parameters and each output channel is configured using FC 223 (Analog Output CH) to set indivdual output channel parameters such as engineering units, High/Low alarm limits, default value in event of loss of communication with controller, etc.

D/A resolution of each channel is 12 bits. The AO01 module has one D/A converter for each output channel.

The AO01 module will also detect an open circuit in less than 5 seconds.

Features and benefits

  • 16 independently configurable channels supporting:
  • Hi Lvl: 4 to 20 mADC, or 1... +5 VDC
  • Each ouput CH has a dedicated D/A converter
  • 12-Bit D/A converter resolution
  • Accuracy is ±0.1 of Full Scale Range (FSR) where FSR = 25 mA or 6.25 VDC
