Product Details:

FOXBORO 220S-3F6 is a high precision signal converter from the 220S series, a professional signal transducer designed for bridging pneumatic instruments and electronic control systems in process automation. This signal converter realizes bidirectional signal conversion between 3~15 psi pneumatic signal and 4~20mA electronic current signal, solving the compatibility problem between traditional pneumatic field instruments and modern electronic DCS or PLC control systems. The unit adopts compact and rugged metal housing structure, which protects the internal precision sensing and conversion components from vibration, dust and humidity in harsh industrial sites. Operators can reconfigure the measuring range directly on site without returning the device to factory, bringing great flexibility for system commissioning and adjustment.

This FOXBORO 220S-3F6 signal transducer supports two conversion directions. It can convert pneumatic measurement signals from pneumatic transmitters into standard 4~20mA analog current signals and transmit them to electronic control systems. It can also convert 4~20mA control signals output by electronic controllers into 3~15 psi pneumatic signals to drive pneumatic valve actuators. The built-in high-precision sensing assembly ensures stable conversion accuracy during long-term continuous operation. The signal conditioning circuit effectively suppresses external electromagnetic interference, avoiding signal distortion and measurement deviation in complex industrial electromagnetic environments.
