The BIZ-21 intrinsic safety barrier is a specialized device designed to ensure explosion-proof connection of sensors installed in hazardous (explosive) zones to control and monitoring systems located in a safe area.

💡 The BIZ-21-T02 barrier is intended for signal protection of:

Resistance thermal transducers (four-wire circuit)

⚙️ Key Features:

Protection of signal lines (input/output) between safe and hazardous zones
Galvanic isolation between zones
Limitation of current and voltage to levels incapable of causing sparks or heating that could ignite a hazardous atmosphere

Number of channels:

Protection level:
