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-AO1 barrier is intended for signal protection of:

Direct current signals: 0–5 mA
DC voltage signals: 0–10 V
Discrete signals powered by 24 VDC with a maximum continuous switching current up to 10 mA
Digital interface: RS-485

⚙️ 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:
