Product Description
The 130M-N4 is a robust pneumatic controller from the Foxboro 130 Series Consotrol product line. It is designed to provide precise Proportional plus Reset (PI) control in applications where electronic instrumentation is impractical or unsafe. Using a proven force-balance pneumatic mechanism, the controller converts process measurement signals into a standard pneumatic output, delivering high repeatability with minimal hysteresis.
Optimized for panel mounting, the 130M-N4 features a clear, easy-to-read indication of setpoint and process variable. Its fully pneumatic construction makes it inherently explosion-proof, ideal for legacy system support and localized control loops in remote or hazardous industrial environments.

Technical FAQ
Does the 130M-N4 require clean instrument air?
Yes. For reliable operation and to prevent internal orifice blockage, the supply air must be clean, dry, and oil-free, in accordance with ISA instrument air standards.
Can the controller be switched between Automatic and Manual modes?
Yes. The 130M-N4 includes an integrated Auto/Manual transfer mechanism that allows bumpless switching during startup, tuning, or troubleshooting.
