METZ CONNECT 1102830530 Interface Relay White 24 V DC 2 CO 8 A

Control cabinet builders and industrial electricians often need a dependable switching element that can handle moderate loads while providing galvanic isolation between control and power circuits. The METZ CONNECT 1102830530 interface relay answers that call with a compact, plug-in design and a robust 2 CO contact set. Its 24 V DC coil makes it a natural fit for PLC outputs and automation systems, while the white housing keeps it visible in crowded panels.

Why choose it

This relay combines proven AgNi contacts with a flux-proof housing, ensuring reliable switching even in dusty or humid environments. Its low coil power of just 0.4 W reduces thermal load inside enclosures, while the 8 A rating covers a wide range of solenoids, contactors, and signal loads. The plug-in design speeds up installation and replacement, minimizing downtime during maintenance.

Ideal use cases

• Interfacing PLC outputs to motors, valves, and lamps
• Galvanic isolation in industrial control panels
• Signal multiplication and amplification
• Building automation and HVAC control
• Replacement for standard interface relays in existing sockets

Good to know

The relay is designed for use with industry-standard 8-pin octal sockets. Always verify coil polarity for DC operation. For inductive loads, consider adding a suppression diode or RC snubber to extend contact life. The white color aids visibility in dark enclosures but does not affect electrical performance.
