Description HSCM-R400ML Honeywell Carbon Monoxide Detector Honeywell HSCM series carbon monoxide sensors are mainly used to detect carbon monoxide concentration in indoor air where carbon monoxide is generated in parking lots and other places. The sensors can output analog signals and switching signals. and can also transmit detection data through the Modbus RTU protocol for ventilation control. Features: ➢ Use eco-friendly electrochemical carbon monoxide sensor. ➢ Optional display function, LCD digital display shows clearly. ➢ Optional alarm relay output, and the alarm concentration value can be set by dip switches. ➢ Multiple software and hardware protection design ensures high stability. ➢ Integrated RS485 terminal resistor to facilitate on-site debugging (Modbus models only). ➢ RS485 isolation design can isolate high voltage and enhance immunity to ground loops and common-mode signal interference (Modbus models only).
