4-20mA Isolators & Splitters
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.
