When your application requires a very specific control system, look to the T5221 Adjustable Ratio I/P, E/P Transducer. The T5221 Transducer is an electro-pneumatic device that converts a DC current or voltage input signal to a proportional output pressure. This device is made up of four sections, the Signal Conversion Section, the Pneumatic Section, the Ratio Section, and the Booster Section. The Fairchild T5221 I/P transducer has all the response and flow performance features of the T5200 series, with the addition of an Adjustable Gain from the ratio section, which allows this single device to cover most industrial and process control requirements. The output pressure is a function of signal pressure times the ratio of lever arm lengths on either side of the Pivot.

The T5400 Transducer is a digital-pneumatic device that provides a pneumatic output signal controlled by 8 bit digital data instructions from a central control room, a remote control location, or a local control station. This device is made up of two sections, the Signal Conversion Section and the Pneumatic Section. The Signal Conversion Section (PC Board) accepts an 8 bit parallel wired digital signal. Full scale output is divided into 255 parts and the output level is based on the logic state (high or low) of the 8 bits. An enable line allows the unit to accept information from a parallel bus. The digital input signal is converted to an analog signal. The signal is then applied to the actuation mechanism. The Fairchild T5400 Fail Safe High or Low will return the 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 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.
