RS485 Repeaters, Separators, Isolators & Signal Boosters

Extend, isolate, and strengthen your RS485 network without compromise. Is your RS485 bus experiencing stability issues, exceeding 1200 meters, or overloaded with devices? Our industrial RS485 repeaters and galvanic separators are the intelligent solution. Featuring Automatic Data Direction Control, they offer true "Plug & Play" functionality with no software changes required. Powerful 3000 VDC isolation protects your system from surges and ground loops, while the repeater function allows you to double your network's range and device count.

When is an RS485 Repeater or Separator Essential?

Even a well-designed RS485 bus has its physical limits. Our devices are necessary when you need to:

• Exceed the 1200-meter distance: An RS485 repeater actively regenerates and boosts the signal, allowing you to create another network segment of up to 1.2 km.

• Connect more than 32 devices: The device acts as a repeater to create a new, electrically isolated segment, allowing you to expand your system beyond the standard node limitation.

• Protect equipment from damage: In systems with multiple power sources, a galvanic separator is critical. It breaks ground loops and protects communication ports from damage caused by potential differences.

Automatic Direction Control – Hassle-Free Installation

Our RS485 repeaters eliminate the most common issue in half-duplex networks. An integrated hardware circuit automatically manages data transmission direction, which means:

• No software changes needed: Setup is instant and requires no modification to your master device's code.

• Guaranteed stability: It prevents data collisions and ensures reliable communication at any speed up to 115200 bps.

Choose the Level of Protection That Fits Your Needs

We offer two models so you can optimize the cost and safety of your installation:

• R01 Model (Full 3-Way Isolation): Provides 3kV DC isolation between both RS485 ports and the power supply. This is the no-compromise solution for the most critical industrial systems.

• R02 Model (Single-Side Isolation): Offers 3kV DC isolation on one of the RS485 ports, sharing a common ground with the other. This is a smart and cost-effective choice when you need to protect one segment of the network.
