## Long description

The Finder 39.11 MasterBASIC is a high-performance 6.2 mm slim coupling relay module designed for efficient signal isolation and switching in industrial automation environments. Featuring an electromechanical output with a 1 CO (SPDT) contact configuration, this device is engineered for reliability and space-saving integration within control panels. It operates seamlessly on 24V AC/DC power, making it a versatile interface solution for various control systems.
Advantages
The primary benefit of this relay is its ultra-slim design, which allows for high-density mounting in limited spaces, significantly optimizing control panel real estate. Its electromechanical construction ensures robust switching performance for a wide range of industrial loads. The inclusion of screw terminals facilitates secure and straightforward wiring, while the ability to bridge terminals A1 and A2 simplifies common connection tasks, reducing installation time and complexity.
Suitable for
Signal isolation between control systems and field devices
PLC input and output interface applications
Switching small to medium-sized industrial actuators
Automation control panels with limited mounting space
This relay may not be suitable for applications requiring high-frequency switching, where solid-state relays would be more appropriate to prevent mechanical wear. It is also not intended for environments exceeding its IP20 protection rating without additional enclosure protection, nor for switching loads that exceed the 6A current or 1500 VA power capacity.
Key specifications
Contact configuration: 1 CO (SPDT)
Rated current: 6A
Nominal voltage: 24V AC/DC
Switching capacity: 1500 VA (AC1)
Maximum switching voltage: 250V AC
Width: 6.2 mm
Operating temperature: -40 to +70 °C
Protection rating: IP20
Installation involves mounting the module onto a standard DIN rail. Ensure the power supply matches the 24V AC/DC requirement before connecting the control and load wires to the designated screw terminals. The design allows for easy bridging of common connections, which should be performed using compatible jumper links to maintain electrical integrity.
What to consider before purchase
Verify that the 24V AC/DC control voltage is compatible with your existing system
Ensure the 6A switching current is sufficient for your specific load requirements
Check that the operating environment is within the -40 to +70 °C temperature range
Confirm that the IP20 rating is adequate for your installation environment
For optimal longevity and performance, ensure that the relay is installed in a well-ventilated area and that all screw terminals are tightened to the manufacturer's recommended torque specifications to prevent loose connections.
