Product Details:

FOXBORO 130M-N5-D is a single-loop pneumatic indicating controller from the classic 130M series, a premium industrial instrumentation built for process automation. This pneumatic controller adopts precision machined mechanical pneumatic assemblies and sturdy metal housing, protecting internal precision components from vibration, dust and mild corrosive gas in heavy industrial sites. The front panel equips a large analog dial, which can display real-time process variable and setpoint simultaneously, allowing field operators to monitor running status and adjust parameters directly on the unit conveniently. The suffix D stands for derivative function enhancement, fully enabling derivative action to improve dynamic response for fast-changing process loops.

This FOXBORO 130M-N5-D pneumatic controller accepts standard 3~15 psi pneumatic measurement signal from field transmitters that detect temperature, pressure, flow or liquid level. It executes PID control algorithm and generates 3~15 psi pneumatic output signal to drive pneumatic valve actuators, forming complete closed-loop field control. It features bumpless auto-manual transfer function. Operators can freely switch between automatic control mode and manual output adjustment mode without sudden signal jump, avoiding disturbance and keeping continuous production stable. It supports local setpoint adjustment and can receive remote pneumatic setpoint input to match different system configuration requirements.

Without electronic circuit boards, this pneumatic controller provides excellent electromagnetic interference resistance. It is a reliable selection for explosion hazardous locations where electronic instruments cannot work safely. The internal modular mechanical structure supports simple routine inspection, disassembly and component replacement, effectively cutting maintenance workload and plant downtime. This process regulator is widely applied in oil & gas, chemical refining, power generation, pulp and paper industries. It can be deployed for new automation project construction, and also serves as spare parts to replace aging pneumatic control equipment on site. Every FOXBORO 130M-N5-D pneumatic controller is fully calibrated before delivery to maintain consistent and stable long-term performance for process automation.
