Type 900X Miniature I/P, E/P Transducer for Electronic Air Pressure Control Self-correcting to maintain precise control The Type-900X I/P, E/P transducer converts an electrical signal (current or voltage) to a proportional pneumatic output. Utilizing closed-loop pressure feedback circuitry, it provides precise, stable pressure outputs to final control elements. Immunity to vibration effects or mounting position, high tolerance to impure air, and low air consumption make this unit ideal for demanding applications. The compact housing, accessible ports and easy adjustments make it perfect for constrained spaces. An integral volume booster provides high flow capacity, increasing control speed in critical applications. Features •Electronic Closed-loop Feedback Minimizes effects of vibration, mounting position, temperature and supply pressure •Compact Size Great for high density mounting •Easy Wiring Conduit, terminal block or DIN 43650 connections •Input/Output Ports on Front and Back Provides flexible pneumatic connections •Other Features Field selectable outputs (optional), field reversible, RFI/EMI protection, external orifice, supply pressures up to 130 psig •Intrinsic Safety Approvals Standard feature for 4-20mA units: Factory Mutual (FM), Canadian Standards Assoc. (CSA) Optional feature for 4-20mA units: ATEX Available with zero-based ranges
