Finder 38.51.7.012.0050 Relay Interface Module, 1 CO 6A, 12V DC, 6.2 mm Width

The Finder 38.51.7.012.0050 is a slim 6.2 mm wide relay interface module designed for efficient signal switching in industrial automation. This compact device integrates a relay and a screw terminal socket, providing a space-saving solution for control cabinets where high-density component mounting is required. It ensures reliable galvanic isolation and signal conversion between electronic controllers and field devices, featuring a 12V DC coil voltage and a 6A switching capacity.

Advantages

The primary advantage of this module is its ultra-slim 6.2 mm width, which significantly optimizes space in electrical panels. The design allows for easy replacement of the internal relay, reducing maintenance time and costs. It offers sensitive control and adheres to safety standards for secure electrical separation. The inclusion of a built-in LED indicator, a freewheeling diode for protection, and a polarity protection diode ensures operational safety and clear status monitoring. Its robust construction allows it to function reliably in a wide temperature range from -40 to +70 degrees Celsius.

Suitable for

• Industrial automation and control systems
• Signal isolation between PLC outputs and field devices
• Space-constrained electrical control cabinets
• Switching low-power loads in automation circuits

This module may not be suitable for applications requiring high-power switching beyond its 6A limit or for environments where the load voltage exceeds 250V AC. It is also not intended for use in high-vibration environments without proper cabinet mounting or in areas requiring higher IP protection ratings than IP20.

Key specifications

• Contact configuration: 1 changeover contact (1 CO)
• Coil voltage: 12V DC
• Rated current: 6A
• Maximum switching voltage: 250V AC
• Maximum switching power: 1500 VA (AC1)
• Width: 6.2 mm
• Operating temperature: -40 to +70 °C
• Protection rating: IP20

The module is designed for DIN rail mounting. To use it, secure the unit onto the rail, connect your control signal wires to the input terminals, and connect your load to the output terminals using the integrated screw connections. Ensure the coil voltage matches your control system output of 12V DC before powering the circuit.

What to consider before purchase

• Verify that your control system output provides 12V DC.
• Ensure the load current does not exceed 6A.
• Check available space on the DIN rail to accommodate the 6.2 mm width.
• Confirm that the operating environment is within the specified temperature range.

For optimal performance and longevity, ensure that the screw terminals are tightened correctly to prevent loose connections and verify that the load does not exceed the maximum switching capacity of 1500 VA.
