Reliable 4-20mA Signal Isolation with Acromag’s 3-Wire DC Powered Isolators Solutions

Acromag offers a versatile range of 3-wire DC Powered 4-20mA signal isolators.  Designed for precise signal conditioning, noise elimination, and reliable data transmission in industrial environments. These isolators are ideal for isolating field signals from control systems.  As well as protecting sensitive equipment from ground loops and electrical interference.

The line up includes:

  • Model 340i: A cost-effective isolator that delivers high accuracy and dependable performance in general-purpose applications. Designed for DIN-rail mounting.  The 340i provides 3-way isolation.  In addition, it is ideal for isolating a 4-20mA signal loop between field devices and control systems.

  • TT236 Series: A high-performance transmitter that not only isolates but also converts signals with exceptional precision. The TT236 is a compact and rugged 3-wire isolator suitable for use in harsh environments or confined control cabinets.

  • Model 611T and 612T: The 611T is a single-channel signal isolator.  It provides three-way isolation between input, output, and power. The 612T offers two independent isolated channels within a compact housing.  With each channel providing the same high-performance signal isolation. Both models feature fast response times, low power consumption, and are ideal for high-density, space-constrained applications.

Each model supports standard 3-wire powered operation, making them easy to integrate with PLCs, DCS, and other instrumentation systems. Whether for basic loop isolation or more advanced signal processing, Acromag’s signal isolators offer dependable performance and field-proven reliability.
