SAMSON 6111 Industrial Electro Pneumatic Converter I/P Signal Converter 4-20mA Control Valve

Product Overview

The SAMSON Type 6111 is a robust, two-wire electropneumatic converter that transforms a 4–20 mA control signal into a proportional pneumatic output. It is explosion-proof (Ex ia) and built for reliable operation in harsh industrial environments. The compact design and low air consumption make it a standard choice for interfacing electronic DCS/PLC systems with pneumatic control valves and positioners.
