RS232 to RS485 Converters

( number of products: 4 )

Effortlessly extend the range and capabilities of your serial network.

Transform a limited RS232 port into a powerful, multi-drop RS485 network reaching up to 1.2 km. Our industrial RS232 to RS485 converters guarantee reliable data transmission with zero software modifications. Thanks to the built-in Automatic Data Direction Control (ADDC), installation is pure "Plug & Play".

Choose a model with full 3-way 3kV galvanic isolation for ultimate equipment protection in harsh industrial environments.

Forget About Integration Problems

The RS232 standard is reliable but limited to point-to-point communication over short distances. Our interface converters intelligently solve this problem, opening the door to building extensive industrial RS485 networks. They are the perfect solution for connecting PLCs, HMIs, SCADA systems, and PCs to remote field devices, sensors, or meters over a kilometer away.


Automatic Direction Control – Your Competitive Advantage

The biggest challenge in RS232 to RS485 conversion is managing the data transmission direction. Our converters do it for you:

  • Zero Software Changes: The integrated Automatic Data Direction Control (ADDC) circuit hardware-manages the data flow, automatically enabling the RS485 driver/receiver. You don't need to modify a single line of code in your application.

  • Maximum Reliability: Eliminating software-based direction control (e.g., via the RTS signal) prevents data collisions and ensures stable communication at any baud rate up to 115200 bps.


Choose the Level of Protection You Need

We understand that every installation has different safety requirements. That's why we offer a range of converters with various levels of galvanic isolation:

  • C10 Model (Full 3-Way Isolation): Provides 3000 VDC isolation between the RS232 port, the RS485 port, and the power supply. This is the no-compromise solution for the most demanding and critical applications, guaranteeing the highest level of protection against ground loops and surges.

  • C11/C12 Models (Single-Side Isolation): Offer 3kV isolation on either the RS232 side (C11) or the RS485 side (C12). This is a smart choice when you need to protect a specific part of your system—like the host PC's port or the entire bus of field devices.

  • C13 Model (Non-Isolated Version): A cost-effective and reliable solution for applications where the network is electrically stable and galvanic isolation is not required.


Engineered for Industry

  • Extreme Temperature Operation: Guaranteed performance in temperatures ranging from -40°C to +75°C.

  • ESD Protection: Built-in safeguards protect the communication ports against electrostatic discharge.

  • Easy Installation: A compact, 17.5 mm wide enclosure with DIN-rail mounting and a built-in, switch-activated 120 Ohm terminator simplify installation in any control cabinet.

  • 3-Year Warranty: A confirmation of the highest quality and reliability.
