IUC-XX-DOP:Dual-Output Isolator         specsheet 

  • High Input-Output-Power Isolation (1500VAC Test)
  • Industry Standard Inputs: 4-20 mA, 1-5 VDC, and more
  • 2 Industry Standard Output: 4-20 mA, 1-5 VDC, more
  • Outputs are isolated from Input and Power but NOT from each other
  • Easy Field Calibration (Typ. calibration time < 2 min. using handheld meter only)
  • Microprocessor Controlled for High Accuracy
  • Two Wire Supply Option for Two Wire Transmitters
  • Power: 117 VAC 50/60 Hz (Optional 24 VDC)
  • High Noise Rejection
  • CSA and NRTL Approved (LR 51078)

The IUC-XX-DOP is a microprocessor controlled isolator which provides two separate 4-20mA outputs.

The 2 outputs are isolated from the Input and from Power but are NOT isolated from each other.

Both outputs are capable of driving 1000 Ohms of load each when configured as 4-20mA outputs.

This unit can be used to ‘split’ a single signal into two separate signals so that in the event that one output signal becomes shorted, through another device or wiring fault, the other output signal remains operational.

Applications include feeding a single control signal to two or more devices (PLC’s, Chart Recorders, etc.)

And allowing one device to be taken out of the loop without affecting the other one.


  • Accuracy/Linearity: +/- 0.3% max., +/- 0.1% typ.
