Product Details:

FOXBORO 130ZY-N4 is a pneumatic indicating radio controller from the classic 130Z series, a robust industrial instrumentation designed for single-loop closed-loop field control. This pneumatic controller adopts precision force-balance mechanical pneumatic components and a durable metal housing, protecting the internal precision parts from vibration, dust and mild corrosive atmosphere in heavy industrial sites. The front panel is fitted with a large clear analog dial, displaying real-time process variable and setpoint simultaneously, allowing field operators to monitor operating status and adjust parameters directly on the unit conveniently. As a radio type controller, it supports remote signal transmission function to meet distributed process control layout requirements.

This FOXBORO 130ZY-N4 pneumatic controller receives standard 3~15 psi pneumatic measurement signal from field transmitters that track temperature, pressure, flow or liquid level variables. It processes signals through built-in PID algorithm and outputs 3~15 psi pneumatic signal to drive pneumatic valve actuators, forming a complete closed-loop control circuit. It is equipped with bumpless auto-manual transfer function. Operators can freely switch between automatic control mode and manual output adjustment mode without sudden signal jump, which prevents disturbance and protects continuous production stability. It supports local setpoint adjustment and can also accept remote pneumatic setpoint input to match different system configuration demands.

Without electronic circuit boards, this pneumatic controller has strong electromagnetic interference resistance. It is a reliable selection for explosion hazardous locations where electronic instruments cannot operate 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 used in oil & gas, chemical refining, power generation, pulp and paper industries. It can be deployed for new automation project construction, and also acts as spare parts to replace aging pneumatic control equipment on site. Every FOXBORO 130ZY-N4 pneumatic controller is fully calibrated before delivery to maintain consistent and stable long-term performance for process automation.
