The Autonics MP5S-4N is a compact 5-digit, 7-segment LED display with an 8 mm character height, capable of showing ranges from -19999 to 99999. It supports 16 operation modes such as Frequency, Revolutions, Speed, Cycle, Time, Ratio, Density, Error, various Length measurements, Interval, and Accumulation, among others. The device covers measurement ranges from 0.0005 Hz to 50 kHz, with time-range-specific ranges from 0.01 to the maximum of each time range, and it can display values from 0 to 99999 or -19999 to 99999 depending on mode. Input can be via voltage input (PNP) or no-voltage input (NPN), and it can be powered by a wide AC range of 100–240 VAC at 50/60 Hz, or an external DC supply up to 12 V with a tolerance of ±10% and up to 80 mA. Main output provides a comparative value indicator. The unit supports multiple input types, including solid-state inputs up to 50 kHz (with minimum pulse widths specified) and contact inputs up to 45 Hz, with specific limits per operation mode. Accuracy varies by mode, with F1/F2/F7–F10 at FS±0.05% rdg±1 digit and F3–F6 at FS±0.01% rdg±1 digit. A prescale function allows direct input values from 0.0001×10^-9 to 9.9999×10^9. Operating ambient conditions range from -10 to 50°C (storage -20 to 60°C) and 35–85% RH (storage 35–85%). The device weighs about 191 g (approximately 132 g for the main unit) and carries an IP54 front-panel protection rating.
