BRAUN D124.1S2U2M Speed and Direction Monitor – Reliable Monitoring for Critical Rotating Equipment

BRAUN D124.1S2U2M is a professional Speed and Direction Monitor designed for continuous monitoring of rotating equipment. The unit works with BRAUN A5S3 series speed sensors to detect rotational speed and direction, providing a direction signal, speed alarm, digital display and analog output. The D124.1S2U2M is supplied in a compact snap-on-track housing and supports an AC/DC power supply of 85–265 V, with an extended operating temperature range of approximately -20°C to +65°C.

BRAUN – German Technology for Rotating Equipment Protection

BRAUN GmbH Industrie-Elektronik, Germany, has more than 60 years of experience in speed measurement and protection technology. The company develops and manufactures speed sensors, tachometers, monitoring devices and high-safety protection systems for critical rotating equipment. Its solutions are widely applied in power generation, oil & gas, chemical plants, turbines, pumps, compressors and expanders.

A key BRAUN technology is its Differential-Hall-Effect sensor principle. A5S sensors are contact-free, wear-free and maintenance-free, while being resistant to external magnetic interference and machine vibration. Depending on the series, BRAUN sensors can operate from 0 Hz, allowing speed monitoring down to standstill.

BRAUN A5S Speed Sensor Range

The A5S family includes versions for non-hazardous and hazardous areas, including ATEX, UKEX and IECEx certified variants. BRAUN also states TÜV certification up to SIL3 for applicable A5S speed sensors.

Why Choose BRAUN D124.1S2U2M?

The D124.1S2U2M is particularly useful where incorrect rotational direction, underspeed or abnormal machine operation can create a serious process or equipment risk. Typical applications include turbine turning gear, feeding pumps, compressors and automatic machine testing systems.

BRAUN's newer monitoring platforms provide functions such as sensor monitoring, self-test, plausibility checking, alarm outputs and analog speed output. The E16225D, for example, supports 0–50 kHz, 0/4–20 mA analog output and safety relay outputs.

Applications

BRAUN speed monitoring technology is suitable for:

• Steam and gas turbines

• Turbine turning gear systems

• Feedwater and process pumps

• Compressors and expanders

• Oil & gas equipment

• Chemical processing plants

• Power generation systems

• Industrial rotating machinery

For applications where equipment availability and personnel/process safety are critical, BRAUN combines robust sensor construction, high-quality electronics and safety-oriented monitoring architectures. The A5S sensor housing is sealed stainless steel and pressure-resistant to more than 200 bar at the sensor tip, supporting demanding industrial environments.
