4-20mA Isolators and Splitters

Product Code: IS

Acromag offers the industry's best selection of isolators. Dozens of models are now available to meet your needs. Select from single, dual, and quad-channel models with AC, DC, or loop-powered operation. Signal splitters deliver dual outputs from a single source. And whether you need a unit that sinks or sources current, Acromag has the right solution for you.

Optical or galvanic isolation eliminate ground loop errors, reduce noise, and block high voltage transient surges. All Acromag isolators will withstand 1500V AC for 60 seconds and provide continuous 250V AC or 354V DC common-mode protection of your precious equipment.

Our multi-channel modules reduce costs and save space. Models with push-button calibration simplify installation and maintenance tasks. Units with trim pots ship preset for 4-20mA input/output so field calibration is not required. Series 630T models offer isolated 24V DC excitation on inputs to power your two-wire transmitters.

4-20mA Isolators

Signal isolators receive 4-20mA process current inputs and provide an isolated 4-20mA output signal. One multi-channel units, each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals. Products include

  • 2 Wire loop powered isolators
  • 3 Wire DC Powered isolators
  • 4 Wire AC/DC Powered isolators

4-20mA Splitters

Signal splitters receive a 4-20mA process current inputs and provide two identical isolated 4-20mA output signals. Each channel operates independently and is isolated from the others to prevent interaction between channels. Galvanic isolation eliminates ground loops, reduces noise, and blocks transient signals. Products include

  • 2 Wire loop powered splitters
  • 4 Wire AC/DC Powered splitters

USB Isolators

These compact, industrial-grade isolators provide high-voltage USB isolation to protect computers and instruments from electrical surges, spikes, and noise.
