The IFM DD0203 is a speed monitoring evaluation unit designed to monitor rotational and linear movement. It evaluates pulse signals from external sensors and detects underspeed or overspeed conditions. The unit provides relay and transistor outputs for machine-control integration. Its wide-range power supply supports both AC and DC supply systems. Potentiometer-based adjustment provides simple configuration of speed and monitoring functions.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The DD0203 can evaluate pulse sequences to determine machine speed. The monitoring threshold can be adjusted according to the required application. Overspeed and underspeed monitoring functions allow the device to detect abnormal machine operation. Adjustable startup delay and hysteresis help prevent unwanted switching during machine startup. This makes the device suitable for conveyors, rotating machines and other motion applications.
The device provides a relay output and transistor output for integration into control circuits. LEDs indicate power, input, output and release conditions. The integrated wide-range supply simplifies installation where different supply voltages are available. Plug-in screw terminals provide convenient wiring. Its DIN-rail design allows simple control-panel installation.
