MTT MS3704 Slim Plug-In High-Level Signal Conditioner

Ensure optimal signal integrity and reliable electrical isolation in your industrial automation systems with the MTT MS3704 Signal Conditioner. Engineered into a compact, ultra-slim plug-in design, this high-performance isolator efficiently converts high-level DC current or voltage input signals into standard, universally accepted DC outputs.

Whether protecting sensitive equipment from ground loop currents or splitting a single input into highly isolated dual-channel outputs, the MS3704 delivers industrial-grade performance in a space-saving package.

Key Features

    • High-Level Signal Conversion: Converts a wide array of DC currents or voltage inputs into standard DC system signals smoothly.

  • Flexible Channel Outputs: Available in isolated single or dual output configurations to optimize control loop architecture.

  • Ultra-Slim, Plug-In Form Factor: At just 29 mm wide, its compact footprint maximizes rail density, while the plug-in housing enables rapid hot-swapping or installation.

  • Robust 4-Way Isolation: Thoroughly insulates loops by enforcing galvanic separation between the input, output 1, output 2, power, and ground networks.

  • Enhanced Environmental Resilience: Comes standard with premium polyurethane anti-humidity conformal board coating (HumiSeal® 1A27NS) to protect against harsh environments.
