Phoenix Contact 2864406 3-way Isolating Amplifier

The PHOENIX CONTACT MINI MCR-SL-I-I is a highly compact isolating amplifier designed for electrical isolation, conversion, amplification, and filtering of standard analog signals. This 6.2 mm wide amplifier is ideal for applications requiring electrical isolation and signal conditioning. It offers 3-way isolation, low power consumption, and can be used as an entry-level alternative to configurable signal conditioners. The device supports standard signals 0...20 mA or 4...20 mA on both the input and output sides, electrically isolated. It is commonly used in industrial automation, process control, and data acquisition systems where signal isolation and amplification are crucial for reliable data transmission.
