The Fairchild T7900 Series Electro-Pneumatic Transducers have a closed-loop, integrated, microprocessor control system that regulates outlet pressure. The Model T7900 controls pressure in proportion to an analog electrical input signal. An internal feedback sensor monitors output pressure to achieve high accuracy. You can control the output from the Model T7900 using the keypad or from an analog control signal. You can control the output from the Model T7900D using the keypad and through DeviceNet™ Communication network. With its integral booster section, the T7900 delivers high accuracy at its high flow capacity of 100 SCFM (170 m3/HR)

Fairchild's new T1750 I/P, E/P transducer delivers high performance in terns of its high accuracy, high pressure, high flow and fast response. It operates with the same pinpoint accuracy from 15 psi [1BAR], (150 kPa) output all the way up to 750 psi [50 BAR] (5 MPa) output. This unit moves tremendous air volume, as its 1000 SCFM (1700 m3/HR) flow capacity is second to none. When you need fast response you can rely on the T1750 response time of less than 15 ms. The Model T1750 Transducers have a closed-loop, integrated, microprocessor control system that regulates outlet pressure. You can control the output from the Model T1750 using the keypad or from an analog control signal. The Feed and Bleed Solenoid Valves control pressure in the Signal Chamber of the Booster Section. A pressure sensor measures the outlet pressure and provides a feedback signal to the Electronics Section. Any variation in pressure between the setpoint and the outlet pressure activates the Feed and Bleed Solenoid Valves to change the output pressure.

Specifications:

• Max Supply Pressure: 1000 psig, [70 BAR]
• Max Output Pressure: 750 psig [50 BAR]
• Flow Capacity: 1000 SCFM (1700 m3/HR)

Uniquely designed by Fairchild, the T6100 "Lock in Last Place" I/P transducer provides flexibility, reliability and safety in applications requiring protection from signal failures to critical control system instruments. Its simple yet effective voice coil actuation now Locks in "Last Position" to accurately capture the setpoint with extremely low drift after a power loss permits the T6100 to maintain set point. The unit's IP65 rating allows you to handle moist applications with ease. Design of the T6100 relies on a proprietary integrated solenoid valve module interposed between the flapper-nozzle pilot and the booster section. Upon signal failure, an electrical charge stored within the active electronic circuit controlling the integrated solenoid valve module maintains the current to the voice coil at its last setpoint. Simultaneously, a high energy pulse closes the solenoid valve, trapping the signal pressure within the signal chamber at the last setpoint. The booster continues to provide its normal forward and exhaust flow, with the constant signal pressure now captured and maintained within the signal chamber. Advanced valve orifice design of the T6100 increases its forward flow capacity to a minimum of 5-scfm at 21-psig supply pressure.
