Module RS-485 DCON 1 kênh đầu ra tương tự AO ICP DAS I-7021 CR


  • Current or Voltage Output
  • High Resolution: 12-bit
  • Software Selectable Current or Voltage Output
  • Open Wire Detection for Current Output
  • Readback Voltage or Current
  • Configurable Power-on Value and Safe Value Settings
  • Programmable Output Slope
  • Built-in Dual Watchdog


The I-7021 is a 12-bit and I-7021P is a 16-bit, 1-channel Analog Output module that is designed for both voltage and current output. The I-7021 features 3000 VDC intra-module isolation and the power source for the current output can be selected as either internal or external via a jumper. Options are also provided to allow power-on and safe values to be set. Both support the DCON protocols which can be configured via software.
