The Switch Amplifier is a versatile 2-channel signal conditioner designed for reliable signal processing in hazardous environments. It accepts dry contact or NAMUR inputs and provides a relay contact output, making it suitable for various applications.
The Switch Amplifier from Pepperl+Fuchs is part of a comprehensive family of intrinsic safety barriers, engineered to ensure safe signal transmission in explosive atmospheres. This product is designed to handle various input types, accommodating both dry contact switches and NAMUR sensors, which are commonly used in industrial automation and process control systems.
With a compact housing width of just 12.5 mm, the Switch Amplifier maximizes space efficiency in control panels while delivering reliable performance. It operates on a 24 V DC supply, ensuring compatibility with standard power rail systems. The built-in line fault detection (LFD) feature enhances system reliability by monitoring for potential faults in the signal path, thus maintaining operational integrity even in challenging environments. The device is certified for up to SIL 2 according to IEC 61508, making it suitable for safety-critical applications.
