The HB 6.7 signaling unit is extremely suitable for monitoring the status of your gas distribution system remotely, in combination with contactors. Think of content signaling of your gas cylinders, gas packages, bulk tank or to monitor your line pressure.
As contactors, both (pressure) switches and contact manometers in NO or NC version can be connected.
When the contact is broken (NO) or made (NC), an optical and acoustic signal follows. The acoustic signal can be suppressed using the reset button. The optical signal disappears when the contact is restored.
