Finder 38 Series Interface Relay Module, 1 CO 6A, 12V DC Coil, 6.2mm, Push-in 38.51.7.012.5050

In industrial control panels, space is at a premium and reliable signal conversion is critical. The Finder 38 Series Interface Relay Module (type 38.51.7.012.5050) solves both challenges: it packs a 1 changeover (SPDT) relay with 6 A switching capability into an ultra-slim 6.2 mm DIN rail housing, providing a compact interface between PLC outputs and field devices. Its 12 V DC coil and push-in terminals ensure fast, tool-free wiring, while the integrated LED and protection coil simplify commissioning and diagnostics.

Who is it for

This module is ideal for panel builders, system integrators, and maintenance engineers working in automation, building management, and machinery control. It suits applications where multiple relays must fit in limited cabinet space, such as PLC output isolation, signal amplification, or driving small contactors and valves.

Main features

• Ultra-slim 6.2 mm width saves up to 50% rail space compared to standard relays
• 1 changeover contact (SPDT) rated 6 A / 250 V AC for versatile switching
• 12 V DC coil with low power consumption (0.17 W) and LED status indicator
• Push-in terminals for quick, secure connection without special tools
• High dielectric strength (6 kV between coil and contacts) for safe isolation
• Wide operating temperature range from -40 °C to +70 °C
