Watson Smith NPT 1/4 Female 1.75 L/min I/P & E/P Converters, 1 to 10 V input 0.14 bar to 8 bar 540400R

Watson Smith 540400R I/P & E/P Converters with 1/4 Female NPT Connection deliver accurate pneumatic pressure control using a 1 to 10 V input signal, supporting a maximum flow rate of 1.75 L/min. These converters are designed for demanding industrial environments with an IP65 rating and capability to operate at temperatures up to 60°C.

Featuring a glass reinforced nylon cover and nitrile diaphragms, these converters offer durability and resistance to wear. The integral volume booster enables flow rates up to 4.72 dm3/s (10 scfm), allowing rapid response times typically around 2 seconds (10-90%). Thanks to their minimal vibration and sensitivity to low pressures, they provide precise control for pneumatic systems.

The 1/4 inch female NPT port connection ensures compatibility with standard pneumatic fittings, and the supplied mounting bracket and DIN43650 connector plug facilitate straightforward installation. These proportional converters operate without oil, using dry air filtered to 5μm for clean pneumatic control.

I/P & E/P converters are electro-pneumatic devices that convert electrical signals to pneumatic pressure outputs, commonly used in industrial and process control systems for cylinders, valves, relays, brakes, and clutches. They can be mounted in control rooms or directly on-site, with adjustable zero and span settings accessible from the front face.

The product is certified for hazardous environments with ATEX certification and complies with EN 60079 standards, making it suitable for use in potentially explosive atmospheres. Includes a 1/4 inch female NPT port and mounting accessories.
