Description
The 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.
