รายละเอียดสินค้า / Product Details
Failfreeze Type 422
Proportional current-to-pressure converter using advanced electronic control to achieve outstanding pressure control via a 4-20mA input signal. Fail-freeze operation ensures that the output pressure is retained on power failure or loss of input signal.
Fail-freeze operation
High immunity to vibration
Environmental protection to IP65
Two integral 1/4 NPT gauge ports
Electrical signal: Typically 7.5V

Note
*Inlet pressure must be at least 0.7 bar above output pressure
I/P & E/P Converters
I/P converters are electro-pneumatic instruments that will change pneumatic pressures in response to varying electrical current and voltage input signals. They have extensive application potential in both industrial and process systems, for control of cylinders, valves, valve positioners, relays, brakes and clutches. The converters can be mounted in control rooms or in the field, and have zero and span settings that are adjustable from the front face of the instrument. Failsafe converters are available which will cause the output pressure to fall to <15mbar (0.2 psig) in the event of power failure or loss of input signal.
