Cảm biến đo nồng độ khí CO, CO2 Telasia DCO-S4

• Multi-functional sensing & controlling of CO, temperature or (optional) CO2 in ambient air with programmable control settings.
• • State-of-art electrochemical sensor cell to measure CO gas in parts-per-million (ppm) and NDIR technology to measure CO2.
• • Precision temperature sensor.
• • Saves energy costs with flexible demand controlled ventilation (DCV) strategy.
• • Two relay outputs (normally open contacts) with pre-settings (user adjustable) for complex local ON/OFF and/or stage controls.
• • Temperature/CO2 control and display enable or disable function selects.
• • Fail-safe design with N.C. contacts during power failure.
• • Built-in System Test (ST) function.
• • Long CO sensor cell life with typical maintenance interval > 1 year;
• • Built-in temperature compensation on CO & CO2 measurement.
• • Long CO2 sensor life with built-in automatic background correction (ABC) function.
• • Optional CO, CO2 & Temp analogue output signals (0~10V or 4~20mA) for connection to remote central computer and/or alarm panel.
• • Optional RS485 Modbus connection or wireless Zigbee connection to the gateway.
