Product Details:

FOXBORO 760ISB-A is a microprocessor-based single station controller from the 760 series, a high-performance loop regulator built for process automation. This panel-mounted controller adopts a compact, sturdy metal housing that protects internal microelectronic circuits from vibration, dust and humidity inside control rooms and local field operating stations. The front panel is equipped with a clear digital display and intuitive operation buttons, enabling field operators to check real-time process variable, setpoint and control output value directly. Operators can complete local PID parameter setup, operation mode switching and alarm status checking conveniently on the front panel of the unit.

This FOXBORO 760ISB-A loop regulator accepts multiple standard input signals, including 4~20mA analog current, DC voltage, RTD and thermocouple signals collected from field transmitters for temperature, pressure, flow and liquid level measurement. 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.
