Common Applications
Product Precautions
Foxboro B0123HE regulates instrument-air supply pressure and adds an integral filter element plus a drain feature for pneumatic service.
- Provides one adjustable pneumatic outlet for its adjustable pressure regulator with filter function.
- Handles regulated instrument air through the documented Foxboro system path.
- Works with the pneumatic instrument supply line with the drain kept at the lowest point.
- Clockwise knob rotation raises regulated pressure; counterclockwise rotation lowers it.
The adjustable pressure regulator with filter belongs in the controlled Foxboro architecture and works with the pneumatic instrument supply line with the drain kept at the lowest point. Its mating hardware, wiring, database configuration and final response must be checked together before release.
Important Notice: Use B0123HE only with the pneumatic instrument supply line with the drain kept at the lowest point; verify every interface and the controlled project configuration before energizing or pressurizing the subsystem.

The first document covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance record.
System maintenance
Restores the documented adjustable pressure regulator with filter function in an existing Foxboro control system.
Signal-path service
Supports controlled testing of regulated instrument air at the assigned system position.
Planned replacement
Provides an exact-identity replacement path after the pneumatic instrument supply line with the drain kept at the lowest point has been verified.
Commissioning
Allows the responsible engineer to prove configuration, diagnostics and response for one adjustable pneumatic outlet.
Before installing Foxboro B0123HE, confirm the documented system, interfaces and controlled configuration.
1
Match the complete B0123HE marking to the work order and installed position before removal.
2
Confirm the pneumatic instrument supply line with the drain kept at the lowest point before disconnecting any interface.
3
Keep regulated instrument air within the documented electrical or pneumatic range.
4
Record terminal designations, polarity, common, shield and cable routing before disconnection.
5
Inspect mounting, connector keying, terminal condition and retention hardware before installation.
6
Restore the controlled database, range, alarm, filter and fail-state settings before energization.
7
Review local indicators and controller diagnostics during the controlled startup sequence.
8
Prove the intended response across one adjustable pneumatic outlet and record the acceptance result before release.
Technical notes
Use B0123HE only with the pneumatic instrument supply line with the drain kept at the lowest point; verify every interface and the controlled project configuration before energizing or pressurizing the subsystem.
