## Long description

The Wago 859-304 is a professional-grade terminal block equipped with an integrated 24V DC miniature relay, engineered for precise electrical signal switching in industrial environments. This 1-pole component is housed in a slim 6 mm wide casing, making it an ideal choice for high-density control cabinets where space optimization is critical. By combining secure wire termination with reliable relay functionality, it provides a robust interface for automation systems and control circuits.
Advantages
The primary benefit of this terminal block is its space-saving design, which allows for efficient use of DIN-rail space without compromising on performance. The integrated relay simplifies installation by reducing the need for separate components, thereby streamlining the wiring process and improving overall system reliability. Its compact form factor ensures compatibility with standard industrial layouts, while the high-quality construction guarantees long-term operational stability in demanding electrical applications.
Suitable for
Industrial automation and control systems
Signal switching in PLC-based applications
Space-constrained electrical cabinets
DIN-rail mounted control panels
When it may not be suitable
This component is designed specifically for 24V DC control signals and is not suitable for high-voltage power switching or applications requiring high-current loads. It should not be used in environments that exceed its specified thermal or electrical operating limits.
Key specifications
Nominal voltage: 24V DC
Configuration: 1-pole (1P)
Width: 6 mm
Height: 56 mm
Depth: 91 mm
Mounting type: DIN-rail
How to use
Installation involves snapping the terminal block onto a standard DIN-rail. Wires are connected to the terminal points using standard industrial wiring practices, ensuring that the connections are secure and properly tightened. Once mounted, the relay functions as an interface between the control signal and the load, facilitating automated switching operations within the circuit.
What to consider before purchase
Ensure the control voltage matches the 24V DC requirement
Verify that the DIN-rail space is sufficient for the 6 mm width
Confirm that the load requirements are within the relay's switching capacity
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance on the terminal block to prevent electrical hazards. Periodically inspect the connections for tightness to maintain optimal signal integrity.
