Product details
Explosion-proof Failsafe Type 140
Electronic current-to-pressure converter utilising advanced closed-loop operation to allow accurate high-resolution pressure control via a 4-20mA input signal. Fail-safe operation ensures that output pressure falls to zero on loss of input signal.
ATEX-certified explosion-proof construction
Fail-safe operation
Environmental protection to IP66
Jack socket for on-site monitoring
Field replaceable air filter
Approvals
EEx d IIC T4
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.
