ifm DD2503 Speed Monitoring Evaluation Unit 0.1-1000Hz 110-240V AC / 27V DC DIN Rail

Product Description

The ifm DD2503 is a single-channel evaluation unit designed for monitoring frequency, rotational speed, linear speed, pulses, and machine cycles in industrial applications. It provides reliable overspeed and underspeed monitoring with an adjustable frequency range of 0.1 to 1000 Hz and rotational speed monitoring up to 60,000 pulses per minute. The unit features a bright OLED display and programming buttons for convenient parameter setting and actual-value indication. With two relay outputs, an additional 4–20 mA analog output, sensor supply capability, and DIN-rail mounting, the DD2503 is suitable for conveyors, motors, fans, pumps, shafts, and other rotating or cyclic machinery.

Standard Features

• Speed and frequency monitoring: Detects frequency, rotational speed, linear speed, pulses, and machine cycles.
• Overspeed and underspeed detection: Provides reliable monitoring of machines operating outside defined speed limits.
• OLED display: Clearly displays actual values and programming information for convenient commissioning.
• Flexible power supply: Supports 110–240 V AC or 27 V DC operation for industrial control applications.
• Dual relay outputs: Provides two switching outputs for alarms, control functions, and machine interlocking.
• 4–20 mA analog output: Enables transmission of measured values to PLCs, controllers, and monitoring systems.
• DIN-rail mounting: Compact housing simplifies installation inside industrial control cabinets.
