Bard 8301-061 - Hydrogen Gas Detector

Bard 8301-061 is an OEM hydrogen gas detector used with PLC-controlled Bard DA and DL Series wall mount units in battery rooms or shelter applications to help manage ventilation when hydrogen accumulates during charging. This detector is designed to sense hydrogen down to about 1 percent by volume, signaling the control system to bring in outdoor air through the economizer and run the indoor blower, and it steps up to a higher level alarm around 2 percent by volume with an audible warning. It is a pre-calibrated, field-ready safety device powered by DC (typically 17 to 60 VDC) with onboard status indication and relay outputs, making it a direct-fit replacement when you need dependable detection and proper interaction with the Bard controller logic.
