The IFM DD2505 is a programmable double pulse evaluation system designed for monitoring rotational speed, frequency and machine cycles. It provides two pulse inputs with one switching point for each input. The device can evaluate machine speed and generate switching signals when configured limits are reached. It supports AC and DC power supply for flexible industrial installation. The compact DIN-rail housing makes the unit suitable for control cabinets.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The DD2505 provides two pulse inputs for monitoring two independent signals or machine conditions. Each input can have its own switching point for flexible speed monitoring. This makes it suitable for applications where two speed signals must be evaluated simultaneously. Relay and transistor outputs provide convenient machine-control interfaces. The programmable design enables adaptation to different machine requirements.
The unit can be used for overspeed, underspeed and acceptable-range monitoring. A test function allows checking of the evaluation system without requiring an external frequency source. LEDs and control functions assist with commissioning and diagnostics. Its wide-range supply simplifies integration into industrial electrical systems. DIN-rail mounting enables easy installation and replacement.
