Relay module Wago UPK-2.2, model UPK-2.2, relay interface module for control systems

The Wago UPK-2.2 relay module is a compact relay interface intended for integration into control and automation systems. It provides electromechanical relay switching to control external loads and to isolate control logic from power circuits. The module is designed for use in industrial automation panels, building management systems and machinery control where reliable electrical separation and predictable switching behavior are required.

Advantages

The module offers a small footprint that facilitates installation in tight panel spaces while maintaining standard relay functionality. Its relay interface design ensures galvanic isolation between input control signals and switched outputs, reducing interference and protecting control electronics. The UPK-2.2 is compatible with common control voltages and supports straightforward wiring, which simplifies commissioning and maintenance.

Suitable for

• Switching of lighting and small motor loads in building automation
• Interfacing control logic with higher-voltage power circuits in industrial panels
• Signal isolation and relay control in machine automation
• Replacement or expansion of relay channels in control cabinets

Key specifications

• Relay type: electromechanical relay outputs for switching external circuits
• Contact configuration: single-channel relay switching (changeover or as specified by manufacturer)
• Mounting: DIN-rail or panel mounting compatible form factor for control cabinets
• Control interface: input terminals for control signals compatible with common control voltages
• Electrical isolation: galvanic separation between control inputs and relay contacts
• Mechanical dimensions: compact module profile suitable for dense panel layouts
• Application environment: designed for industrial and building automation conditions

How to use

Install the UPK-2.2 module on the appropriate mounting rail or within the control cabinet according to local wiring rules. Connect control signal wires to the input terminals and route the external load circuits through the relay contact terminals. Verify all connections are tightened and observe polarity and grounding requirements where applicable. After powering the control system, test relay activation with the intended control signals and confirm correct switching of the external load.

Usage recommendations

Use the relay module within its specified load and switching ratings and follow manufacturer instructions for wiring and mounting. For inductive loads, include appropriate suppression components to protect contacts. Perform periodic inspection of terminal tightness and contact condition as part of preventative maintenance.
