Product Details:

FOXBORO 760-INA-A is a microprocessor-based single station controller from the 760 series, a high-performance loop regulator built for process automation. This panel mount controller comes with a compact rugged metal housing, protecting internal microelectronic circuits from vibration, dust and humidity in industrial control rooms and local operating stations. The front panel integrates an intuitive display and functional operation buttons, allowing field operators to view real-time process variable, setpoint and control output directly. Operators can complete local PID parameter setting, mode switching and alarm checking conveniently on the unit.

This FOXBORO 760-INA-A loop regulator accepts various standard input signals, including 4~20mA analog current, voltage, RTD and thermocouple signals collected from field transmitters that measure temperature, pressure, flow and liquid level. It executes precise PID control calculation and generates isolated 4~20mA analog output signal to drive valve actuators, forming closed-loop loop control to stabilize industrial process variables. It supports bumpless auto-manual transfer function. Operators can switch freely between automatic control mode and manual output adjustment mode without sudden signal jump, preventing disturbance to continuous production process. Built-in self-diagnosis function can detect sensor signal loss, circuit abnormality and hardware faults, and trigger alarm prompts for operators, shortening troubleshooting time and reducing plant downtime.
