Type 1000 - T1000 I/P High Relief Transducer
The Bellofram Precision Controls Type 1000 I/P High Relief Transducer converts a 4-20 mA current signal into proportional pneumatic pressure and adds high exhaust capacity for faster pressure reduction. An integral pneumatic volume booster provides flow up to 12 SCFM, while the high-relief design provides 7 SCFM exhaust capacity at 5 psid. With supply pressure capability up to 100 psig and pipe, panel, bracket, or DIN-rail mounting, it is well suited to valve actuators, positioners, dampers, cylinders, HVAC equipment, and industrial process-control systems that require rapid blowdown.
