Phoenix MINI MCR-SL-U1-21-SP

The Phoenix MINI MCR-SL-U1-21-SP is a highly compact, 6.2 mm wide, 3-way isolating amplifier designed for the electrical isolation, conversion, amplification, and filtering of standard analog signals. It's part of Phoenix Contact's MINI Analog series, known for its space-saving design and reliable performance in industrial applications.

Here's a detailed breakdown:

Product Description

The MINI MCR-SL-U1-21-SP is a versatile signal conditioner. It typically accepts a 0-10 V or 1-5 V voltage input and provides two isolated current outputs, usually 0-20 mA or 4-20 mA. It features 3-way isolation (between input, output, and supply), ensuring robust protection against interference and ground loops. The device is configurable via DIP switches located on the side of the housing, allowing users to select input and output signal ranges, as well as other parameters like filter types and error behavior.
