HiC2422 isolated barrier for analog signals, Pepperl+Fuchs
Products and Solutions
2. 4. 2024

New Universal Isolated Barrier for Analog Signals: HiC2422

The new H-System HiC2422 intrinsic safety barrier has two freely configurable channels for analog signals, which means it can be used both as a SMART transmitter power supply for two-wire transmitters and as a current driver for valve positioners.
