Physical Dimensions and Mounting
This ultrasonic module measures 250 mm in width, 25 mm in height, and 160 mm in depth. The unit weighs approximately 0.45 kg. It plugs directly into a standard SIMATIC S5 rack slot. The front panel includes LED indicators for power, echo quality, and measurement status. These LEDs assist with installation and troubleshooting.
Measurement Principle and Operation
The 6ES5241-3DA12 emits ultrasonic pulses and measures their return time. It calculates the distance based on the sound speed in air. The module features automatic temperature compensation for accurate readings. It filters out false echoes from obstacles and agitators. The integrated signal processing converts the distance into level or volume values.
Sensor Connectivity and Outputs
The module connects to an ultrasonic transducer using a coaxial cable with a BNC connector. It provides an analog output of 0–10 VDC or 4–20 mA for the measured value. The output updates at a rate of 2 times per second. The unit can set two independent switching points for limit detection. It includes a built-in relay output for alarm or control functions.
Installation and Configuration
You can install the module into any free slot in the S5 rack. Place the ultrasonic transducer above the measurement point with clear sound path. Use the programming software to configure the measuring range and output type. Adjust the sensitivity settings for optimal echo detection during commissioning.
Environmental Compliance
This module carries CE marking for industrial use. It complies with RoHS environmental directives. The unit suits standard control cabinet installations with IP20 protection.
