Your Benefits at a Glance

  • Automatic integration into the Demig ecosystem

    Remote I/O stations are seamlessly integrated into Demig process controllers, visualization systems, and control systems. Communication is managed automatically, reducing engineering effort and commissioning time.

  • Decentralized plant structure

    Multiple fieldbus couplers and remote I/O stations can be flexibly distributed throughout the plant. This reduces cabling effort, installation costs, and potential sources of error.

  • Hot-Swappable Replacement During Operation

    The modules' electronics can be replaced while the system is running, without interrupting fieldbus communication or disconnecting cables.

  • Quick, tool-free installation

    Push-in connectors reduce installation time and prevent wiring errors.

  • Built-in Web Server

    Easy configuration, channel simulation (forcing), and error diagnostics in plain text without additional software.

  • Space savings

    With a module width of just 11.5 mm, you can build your control cabinets to be significantly more compact.

Inputs and Outputs

Digital Inputs and Outputs

  • UR20-16DI-P: Digital input module with 16 channels (P-switching). Perfect for space-saving acquisition of numerous sensor and switching signals in the tightest of spaces.
  • UR20-16DO-P: 16-channel digital output module for the reliable control of actuators, valves, or signal LEDs.

Relay Outputs

  • UR20-4RO-SSR-255: Module with 4 solid-state relays (1 A). Guarantees wear-free and extremely fast switching of loads up to 255 volts.
  • UR20-4RO-CO-255: Version with 4 conventional mechanical changeover relays (6 A) for reliable electrical isolation.

Analog Inputs and Outputs with Diagnostics

  • UR20-4AO-UI-16-DIAG: Analog output module (4 channels, selectable current or voltage signal) with 16-bit resolution and integrated channel diagnostics for rapid fault detection in the event of a wire break or short circuit.
  • UR20-4AI-UI-16-DIAG: Analog input module for precise acquisition of standard industrial signals (e.g., 0–10 V or 4–20 mA). 16-bit resolution.
