CP-8500 Electro-Pneumatic Transducer
Brand: Kele
The Kele CP-8500 Series Electronic / Pneumatic Transducers handle a wide variety of pneumatic valve and damper applications that require a 3-15 psig control signal from an electronic controller output.
The CP-8551 is a basic two-wire loop-powered unit with 4-20 mA input.
The CP-8552 is a 3-wire unit with a jumper-selectable input for 4-20 mA, 6-9 Vdc or 0-10 Vdc.
The CP-8511 has a variety of jumper selectable inputs, a pressure gauge, manual override, and 20 Vdc power output for auxiliary components.
Features- Panel or DIN-rail mount for quick Snap-On installation
- High accuracy and low hysteresis for precise control
- Long-term, drift less operation with high repeatability for long life and high performance
- Low air consumption to save energy
- High airflow capacity to handle large pneumatic components and long tubing runs
- Models with field-selectable inputs
- Integral 20 Vdc auxiliary power supply, pressure gauge and manual override on CP-8511
