Bard 8403-096BX - CO2 sensor transmitter with relay
The Bard 8403-096BX CO2 Sensor With Relay is an OEM carbon dioxide transmitter used in Bard HVAC ventilation and IAQ control applications to help the system respond to rising CO2 levels by providing a standard control signal to a controller and a built-in relay output for setpoint based control. This boxed sensor assembly uses NDIR sensing technology and is designed for reliable field service replacement when a failed or drifting sensor is causing incorrect ventilation rates, nuisance alarms, or poor occupant comfort. It supports common building control outputs such as selectable current or voltage signaling and includes a normally open relay contact for simple enable signaling of equipment tied to CO2 demand. Confirm wiring requirements and output configuration in the Bard unit documentation before ordering to ensure proper compatibility.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
