Logic Relay Contact Outputs:
Labconco Logic Biosafety Cabinet (BSC) models are provided with TWO dry relay
contacts to allow connection to an external monitoring system, or to switch other air
handling units “on” when the Labconco unit is turned on.
The Labconco Logic BSC provides two contacts: One to indicate the internal Labconco
blower is on, (so that external blowers may also be energized) and the other to indicate
airflow errors. These contacts provided will “short circuit” when the blower is turned on,
or when there is an airflow error. This means that the Labconco contacts are isolated
from the Labconco equipment, and the user must provide the interface circuitry based
on the requirements of the connected equipment.
The dry contacts are accessed at connector J4 (Labconco harness #38468-00 is
available for easy connection.) This J4 connector is located on the electrical control box
on top of the BSC, as shown in the picture below:
