The 3-digit indicator IMH-1U was designed as a multifunctional transmitter for the top hat rail mounting, for the measuring of voltage, current, temperature and frequency. The configuration happens via three front keys or via the optional PC software PM-TOOL. Optional the indicator can be equipped with a sensor supply, an analog output, 4 switching points, a Bluetooth interface, a data logger and interfaces RS232/RS485 (with Modbus protocol).

DC Voltage Measuring Transducers
A DC voltage measuring transducer captures a DC voltage at its input, scales it and converts it into a standardized output signal — typically 0/4 … 20 mA or 0 … 10 V. This allows DC voltages from sensors, potentiometers or DC sources to be used as process signals in control, regulator or monitoring systems. Many DC-voltage transducers offer galvanic isolation between input and output stages to ensure interference-free signal transmission and prevent ground loops or potential differences.
These transducers are commonly designed as compact DIN-rail modules for easy integration in control cabinets. They are particularly useful whenever a DC voltage must be reliably and stably forwarded over long cable runs or when galvanic isolation is required to maintain signal integrity.
Questions & Answers on DC Voltage Measuring Transducers
What is a DC voltage measuring transducer?
A DC voltage measuring transducer measures a DC voltage input and outputs a standardized analog signal, typically 0/4 … 20 mA or 0 … 10 V.
Why use a DC voltage transducer?
To convert a DC voltage into a universal standard signal that can be processed by controllers, regulators or monitoring systems.
What input voltage ranges can be processed?
Depending on the device, ranges from small voltages (e.g. millivolts) up to higher DC voltages — depending on the specifications of the transducer.
What are common output signals?
Typical outputs are 0/4 … 20 mA or 0 … 10 V, compatible with standard automation and control systems.
Is galvanic isolation provided?
Yes — many DC voltage transducers offer galvanic separation between input and output, ensuring interference-free operation and preventing ground loops or potential differences.
Is an auxiliary supply required?
Yes — in many cases an auxiliary supply is needed to power the input stage, signal processing and output stage.
How precise is a DC voltage transducer?
High-quality devices provide linear and accurate conversion of the input voltage to a stable output signal, with good long-term stability.
Can output signals be transmitted over long cables?
Yes — using standardized signals like 4…20 mA, the output can be sent over long distances without significant signal degradation.
For which applications are DC voltage transducers suitable?
Where DC voltages from sensors, potentiometers, or DC sources need to be converted into standardized analog signals — e.g. in industrial automation, measurement technology, energy or battery systems.
Are there universal models for different voltage input ranges?
Yes — some transducers can be flexibly configured for various input voltages or adjusted using configuration elements to match different measurement tasks.
