The RS series I/O modules integrate bus communication, signal input/output, and I/O power supply into a compact and versatile unit.
Designed for applications requiring 16 or 32 points, the series offers both single-slot and dual-slot configurations.
Featuring a modular design that separates the I/O panel from the communication base, the system supports hot swapping and allows for mixed use of different signal types and terminal interfaces.
The I/O panel accommodates digital, analog, relay, and weighing signals, with three terminal options available: European-style terminals, 3-in-1 terminals, and E-CON connectors, all capable of supplying power to sensors.
Compared to traditional I/O modules, the RS series significantly reduces space requirements.
An optional protective cover enables installation outside the control cabinet in non-water environments.
With its highly integrated architecture and flexible configuration, the RS series provides an efficient and reliable solution for modern industrial automation.
Unlock seamless integration in industrial automation with our I/O modules. Supporting a plethora of protocols like Profinet and EtherCAT, they bridge the communication gap across diverse systems effortlessly.
Split Design for Easy Installation & Maintenance
Our I/O module features a modular split design that simplifies installation and enables effortless future expansion. Digital, analog, relay, and other signal types can be freely mixed and matched on the I/O panel to meet diverse industrial requirements. Individual modules can be replaced or upgraded without affecting the entire system-ideal for dynamic and evolving industrial environments.
Multiple Terminal Types Supported
Our IO modules offer compatibility with various terminal types, allowing flexible wiring configurations to meet diverse application needs. Choose the connection that works best for your system.

Any combination of signal types
In the double - slot version, freely select from digital, analog, relays, and weigh modules for your I/O panels, creating a flexible system tailored to your needs.

With three mounting options like transverse rail, vertical guide rail, and screw mounting, plus a 60% space - saving design, our I/O modules offer unmatched flexibility and compactness.
Cabinet-External Mounting with On-Site Diagnostics
Designed for convenience, these modules support cabinet-external mounting, enabling engineers to perform real-time fault diagnostics and maintenance without interrupting cabinet operation.
