H2CON-6 is especially suited for H2 gas level detection, Ventilation Control & Alarm applications in Battery rooms,Hydrogen Storage and handling areas where there is a danger of Hydrogen accumulation resulting in explosive atmosphere. Its Microcontroller scans each of the six sensors with a fixed alarm threshold of 1 % 2% and >2.5% and gives control/alarm outputs up to three relays and also on LED front panel indicators. These outputs can then be used for Ventilation fan control, Hooter or Overriding shut-down of Charging etc. for the system to take early safety measures. Front panel LED bar graph indications for each channel is provided , thus exact location of fault can be identified. An optional feature of H2CON-6 is that it can be connected over an Isolated RS485 bus with MODBUS protocol.
