RS-485/RS-232 Repeaters, Isolators, Separators & Signal Amplifiers

( number of products: 4 )

Eliminate issues with range, noise, and ground loops in your serial networks.

Whether you need an RS-485 Repeater, a Galvanic Isolator (Separator), or an RS-232 Signal Amplifier, our industrial solutions deliver.

These compact, DIN-rail mountable devices guarantee stable communication and act as powerful isolators, shielding your critical infrastructure from power surges with galvanic isolation (up to 3kV).

It's an investment in operational resilience, eliminating the risk of downtime and equipment damage.

When Do You Need a Repeater, Isolator or Separator?

Every serial installation, whether RS-485 or RS-232, has its limits. Our devices are essential when you need to:

  • Exceed the distance limit: An RS-485 repeater actively regenerates the signal to double the standard 1200m range, while an RS-232 amplifier strengthens the signal for longer cable runs.

  • Connect more than 32 devices (for RS-485): Each device creates a new, electrically isolated segment, enabling you to add another 32 nodes to the network.

  • Protect equipment from damage: Acting as a galvanic isolator or separator, our device physically separates network segments. It's the ultimate protection for RS-485 & RS-232 ports on PLCs and PCs against potential differences and damaging ground loop currents.

Key Benefits of Our Repeaters & Isolators

By choosing devices from Redisage, you gain peace of mind backed by robust features:

  • Protective Function (Isolator/Separator): Galvanic isolation up to 3kV DC and built-in surge protection effectively shield your network and safeguard your valuable equipment from damage.

  • Boosting Function (Repeater): Full digital signal regeneration ensures that no data is lost or corrupted, guaranteeing signal integrity across extensive networks.

  • Quick & Easy Installation: The compact, DIN-rail mountable design saves valuable space and allows for instant installation. Combined with automatic baud rate and data flow detection, setup is a true Plug & Play experience.

Build a Complete and Resilient Network Architecture

An isolator or repeater is a critical part of a reliable system. Combine it with our complementary solutions:
