Ensure reliable signal conversion and high-grade electrical isolation in your control loops with the professional MTT MS3704IS Slim Plug-In High-Level Signal Conditioner (Isolator). Engineered specifically for processing critical automation loops, this compact module seamlessly converts standard 1 to 5V DC voltage or 4 to 20mA DC current process signals into isolated 1 to 5V or 4 to 20mA outputs.

Key Features & Advantages:

  • Standard Process Signal Matching: Specialized for direct 1-5V DC and 4-20mA DC high-level signal configurations, ensuring complete compatibility with industrial transmitters and control loops.
  • Galvanic 4-Way Isolation: Establishes complete galvanic separation across the input, output, power, and ground circuitry to prevent equipment damage from volatile ground loop currents.
  • High-Density 29mm Profile: Space-saving plug-in housing minimizes cabinet footprint while simplifying field replacement or hot-swap calibration tracking.
  • Flexible Field Powering: Multi-power ordering configuration format supports standard plant utilities including 100-240V AC, 24V DC, or 100-240V DC networks.
  • Harsh Climate Defense: Built standard with a polyurethane anti-humidity board coating (HumiSeal® 1A27NS) to maintain stable long-term operation in humid, dusty, or corrosive environments.
