Product Details:

FOXBORO 762CSA-3A is a shelf-mounted single station micro controller belonging to the 762C series, a high-performance loop regulator built for process automation. This controller adopts a robust metal shelf housing instead of panel mounting design, protecting internal microprocessor circuits from vibration, dust and humidity inside control rooms and local operating stations. The front panel is equipped with a readable digital display and function keys, enabling field operators to view real-time process variable, setpoint and control output. Operators can adjust PID parameters, switch operation modes and check alarm status directly on the device conveniently.

This FOXBORO 762CSA-3A loop regulator accepts various standard input signals, including 4~20mA analog current, DC voltage, RTD and thermocouple signals from field transmitters used to measure temperature, pressure, flow and liquid level. It executes precise PID control calculation and provides 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, avoiding disturbance to continuous production process. Built-in self-diagnosis function can detect sensor signal loss, circuit abnormality and hardware faults, triggering alarm prompts for operators to shorten troubleshooting time and reduce plant downtime. The unit uses quick-disconnect multi-pin signal connectors for fast wiring and replacement.
