High-Precision AC & DC Voltage Transmitters
A high-performance voltage transmitter is an essential component in modern industrial control systems. It is designed to safely and accurately measure electrical potentials. Often called voltage transducers, these devices bridge the gap between high-voltage fields and sensitive monitoring equipment. They convert input AC or DC voltages into proportional, standardized analog signals. Common outputs include 4-20mA, 0-5VDC, or 0-10VDC. By incorporating advanced galvanic isolation, a voltage signal converter ensures high operational safety. This protects PLCs and SCADA systems from dangerous spikes and ground loop interference.

How to Select the Right Voltage Signal Converter
Choosing the correct converter is essential for ensuring system compatibility and measurement accuracy. When evaluating a voltage transmitter for automation, buyers should consider several key technical specifications. These factors will help match your specific PLC or SCADA system requirements.
| Selection Factor | Description | Key Considerations |
| Input Voltage Range | The type and magnitude of the voltage being measured. | AC vs. DC, low voltage (mV) vs. extreme high voltage (up to 1500V DC). |
| Output Signal | The standardized signal sent to the control system. | Analog (4-20mA, 0-5VDC, 0-10VDC) vs. Digital protocols. |
| Mounting Preferences | How the device will be installed in the control panel. | Standard 35mm DIN Rail mount vs. secure Panel Mount options. |
| Communication Protocols | Digital integration requirements for SCADA/IoT networks. | Modbus-RTU, Modbus-TCP, or HART compatibility. |
