The BRG-412 galvanic isolation block is designed for:

• 🛡 Galvanic protection of electrical circuits operating with standardized analog signals;
• 🔄 Signal conversion from passive to active current (4–20 mA) for further use in measurement and control systems;
• ✅ Improving the reliability and safety of automation and process control systems by eliminating the effects of electromagnetic interference, potential shifts, and transients.

The device provides dual independent galvanic isolation, allowing two analog signals to be processed simultaneously without mutual influence.
Power is supplied via the 4–20 mA current loop.

Functional Features:

• 🔒 Dual-channel galvanic isolation between inputs and outputs, as well as between the channels;
• 🛡 Signal protection against overvoltage, induced noise, and industrial electromagnetic interference;
• 🔄 Signal conversion from a passive input to an active 4–20 mA output;
• ⚡ Stable and accurate signal transmission even in harsh industrial environments;
• 🔋 Current loop powered, simplifying installation and increasing operational reliability.

Electrical Characteristics:

• ⭕ Number of channels: 2 independent;
• ⭕ Input: 2 passive, standardized, current 4–20 mA;
• ➡ Output: 2 active, standardized, current 4–20 mA;
• 🛡 Galvanic isolation: complete electrical separation between inputs and outputs, as well as between channels;
• 🔋 Power supply: via 4–20 mA current loop.
