Finder 38.51.0.240.0060 väzbové relé 1 CO 6 A 240 V AC DIN lišta

The Finder 38.51.0.240.0060 is a coupling relay engineered for reliable signal isolation and power switching in industrial control systems. Its single changeover contact handles loads up to 6 A at 250 V AC, while the 240 V AC coil with integrated varistor protection ensures stable operation even in electrically noisy environments. The green LED indicator provides immediate visual confirmation of coil status, simplifying diagnostics and maintenance.

Advantages

This relay excels in applications demanding high electrical isolation and long service life. The AgNi contact material offers excellent resistance to welding and arc erosion, supporting up to 100,000 electrical operations at full load. The 6 kV dielectric strength between coil and contacts guarantees safe separation of control and load circuits, while the wide operating temperature range from -40 °C to +70 °C allows deployment in harsh conditions. DIN rail mounting and screw terminals enable fast, secure installation without special tools.

Suitable for

• Isolation of PLC outputs from high-power loads
• Signal multiplication and level adaptation in automation panels
• Interfacing between different voltage systems (e.g., 240 V AC control to 24 V DC logic)

Recommendations

For optimal performance, ensure the coil is driven by a clean 240 V AC supply and that load currents do not exceed 6 A resistive. Use appropriate wire ferrules on screw terminals to maintain reliable connections. When switching inductive loads, consider adding external snubber circuits to extend contact life. This relay is ideal for panel builders seeking a compact, high-isolation interface solution.
