The Switch Amplifier is a robust 2-channel isolated barrier designed for use in hazardous environments. With a 230 V AC supply, it supports both dry contact and NAMUR inputs, ensuring versatility in various applications.
The Switch Amplifier from Pepperl+Fuchs represents a critical component in the field of intrinsic safety barriers, enabling reliable signal transmission in hazardous areas. This device is engineered to offer high levels of isolation between the input and output, ensuring that any faults in the field wiring do not pose a risk to the safety of the overall system.
Commonly used in industrial automation and process control applications, the Switch Amplifier provides passive transistor outputs that are non-polarized, making it suitable for a variety of control scenarios. The device also features line fault detection (LFD) capabilities, enhancing safety by monitoring the integrity of the connections. With a reversible mode of operation and compliance with SIL 2 according to IEC 61508 standards, this amplifier is well-suited for demanding operational environments.
