LED is visible in almost any application environment Compatible with Proportion-Air electropneumatic valves and transducers. DESCRIPTION The PM-4 is a 4 1/2 digit, high accuracy LED panel meter designed to work with Proportion-Air's QB/BB electropneumatic control valves and transducers. The meter is capable of receiving single ended voltage, differential voltage, and sinking current input. It features a large LED display that is visible in virtually any light or industrial environment. DIMENSIONS FRONT BEZEL Input Impedance: Normal Mode Rejection: >1 megohm 120dB at multiple of 50/60Hz Common Mode Rejection: 86dB at DC; greater than Common Mode Voltage: Depends on range of 20dB at multiples of 50/60Hz unit, but is typically +10VDC Accuracy: 0.1 percent of reading Zero Stability: Autozeroed +10µV at all ranges; +1µV/°C typical Conversion Rate: 2.5 readings per second Polarity: Automatic Overload Indication: When input exceeds full scale on any range, the most significant "1" digit and "+" or "-“ symbol is with all other digits blank. Power Requirements: +8 to +18VDC at 225mA Warmup Time: 10 seconds to specified accuracy Operating Temperature: 0°C to +60°C Temperature Coefficient: 5PPM/°C ratiometric ORDERING INFORMATION SIDE VIEW *Current indicators are available for use with the DSI. If current indicator is desired for use with a BB or QB unit, a sourcing output option must be incorporated in the model number, S216 for BB series or S589 for QB series. PROPORTION-AIR, INC.
