MPN / SKU: DD2503 Also known as: IFM DD2503 speed monitor / pulse evaluation unit / rotational speed monitor. DD2503 Applications The DD2503 is a microprocessor-based evaluation unit for speed monitoring. It monitors frequency, rotational speed, speed, pulses and machine cycles from a connected sensor, with a settable range of 0.1...1000 Hz (1...60000 imp/min). Two relay outputs and one 4...20 mA analogue output signal the process condition. The unit mounts on a 35 mm DIN rail, is powered by 110...240 V AC/DC, shows values on an OLED display and operates across -40...60 °C for demanding industrial monitoring.
