The WEIDMULLER UR20-4RO-CO-255 module (part number 1315550000) is a remote I/O solution designed for reliable switching of electrical loads in industrial control cabinets. Part of the u-remote UR20 range, it adds four relay outputs to your automation system, allowing you to control contactors, solenoid valves, heaters, or motors with robust galvanic isolation. Its modular design fits a logic of progressive installation expansion, where each module can be added or replaced individually without disrupting the entire station.

Key features

• 4 relay outputs for digital control signals
• Switching capacity of up to 6 A per channel, 24 A total per module
• IP20 rated housing, suitable for control cabinet mounting
• Manufacturer part number 1315550000 for easy identification and reordering
• Direct integration into WEIDMULLER u-remote UR20 stations

Thanks to its power relay contacts, this module is suitable for both resistive and inductive loads, within the specified current limits. It is ideal for control applications where galvanic isolation between control logic and power circuits is required to protect sensitive equipment. Integration into a UR20 station is immediate, offering a consistent architecture that simplifies wiring and preventive maintenance.

Whether you are designing a new machine or replacing an existing module in an operating installation, part number UR20-4RO-CO-255 ensures proven operational continuity. Its compact format helps optimize space in the cabinet, while its robustness ensures longevity suited to frequent switching cycles in demanding industrial environments. Combined with other I/O modules in the UR20 range, it forms a reliable link for controlling your actuators and managing power signals.
