Phoenix Contact 2864655 2-Channel Loop-Powered Isolator

The PHOENIX CONTACT MINI MCR-SL-2CP-I-I is a highly compact, 2-channel passive isolator ideal for the electrical isolation of current signals without the need for auxiliary power. Its low voltage drop of just 1.7V and design width of only 6.2mm make it suitable for space-constrained applications. This isolator is commonly used in industrial automation, process control, and data acquisition systems to protect sensitive equipment from noise and ground loops while ensuring signal integrity. It supports both 0-20mA and 4-20mA current signals and is designed for reliable performance in harsh environments.
