Model T5420 Digital-Pneumatic Transducer
Brand: Fairchild Industrial ProductsThe Rotork Fairchild T5420 is a Digital-Pneumatic Transducer, compatible with most digital systems using TTL and CMOS Logic.
Its Fail Safe High or Low will return the field reversible output to 3 psig for Direct Acting Mode or to 15 psig for Reverse Acting Mode if the power is lost, regardless of the logic selected.
The Integral Volume Booster Output of the T5420 provides a flow capacity of 45 SCFM (76.5 m3/Hr), to meet input requirements of final control elements requiring a higher capability output signal, increased output pressure, and/or increased flows.
