Optio™ B

MULTI-GAS MONITOR FOR LI-ION BATTERY SAFETY

The Optio B is a stand‑alone multi‑gas detector engineered specifically to monitor Li‑ion battery systems for early signs of thermal runaway. The Optio B uses three dedicated sensors that continuously monitor for carbon dioxide (CO₂), hydrogen (H₂), and volatile organic compounds (VOCs) to before visible smoke or flame appears.

Onboard relays, 4-20mA outputs, and Modbus communication makes it easy to integrate the Optio B with a building automation system (BAS) or battery management system (BMS) for centralized monitoring and alarming.

PRODUCT FEATURES
  • Long Sensor Life – Designed for extended operational longevity, reducing replacement frequency and lowering maintenance costs.
  • Self-Diagnostic Function – Continuously monitors internal health to ensure reliable system performance and early fault detection.
  • Automatic Reset – Recovers seamlessly after power loss, minimizing manual intervention.

  • Onboard Relay Contacts – Provides built-in relays for direct control of external devices, alarms, or ventilation functions.
  • Optional Dual 4–20 mA Outputs – Offers two analog outputs for integration with building management or automation systems.
  • Onboard 80 dB Alarm – Delivers a loud, clear audible warning to alert personnel to hazardous conditions.

  • Bright LCD Display – High-visibility screen ensures clear viewing of gas readings and status information in various lighting conditions.

  • Flexible Sensor Configuration – Supports a combination of internal and remote/external sensors.
