Current to Voltage Converter Module 0/4-20mA to 0-3.3V 5V 10V Voltage Transmitter, Current Transformer Module Signal Conversion Board
Current to Voltage Converter Module 0/4-20mA to 0-3.3V 5V 10V Voltage Transmitter, Current Transformer Module Signal Conversion Board
This current to voltage converter module is specially designed to convert industrial current signals (0-20mA / 4-20mA) into voltage signals (0-3.3V/0-5V/0-10V) so that they can be easily detected and processed by microcontrollers, PLCs or ADC modules. Ideal for long transmission distances where voltage signals lose accuracy - power transmission ensures stability and precision. Main features: Supported current inputs: 0-20mA or 4-20mA Output voltage: 0-3.3V / 0-5V / 0-10V (choose by jumper) Wide supply voltage range: 7V-36V DC (for 10V output >12V required) High-precision scanning: with colour ring precision resistors for minimal temperature drift. Adjustable zero and span: finely adjustable via Zero and SPAN potentiometer. Reverse polarity protection: built-in protection against incorrect wiring. INDUSTRIAL SAFE: High stability, excellent linearity and reliability Application and use: Wiring: supply 7-36V DC according to the terminal designations Power indicator: LED D2 lights up when power is successful. Zero setting: at 0 mA or 4 mA input - adjust zero point with zero potential. Voltage setting: at 20 mA input - set maximum value with SPAN potential. Adjust output voltage via jumper (J1): For 4-20mA Input: 0-2.5V → J1: pins 1-2 & 3-4 plugged 0-3.3V → J1: Pins 1-2 & 3-4 Open 0-5.0V → J1: pins 1-2 & 3-4 plugged 0-10.0V → J1: pins 1-2 plugged in, 3-4 open For 0-20mA Input: 0-3.3V → J1: pins 1-2 & 3-4 plugged 0-5.0V → J1: pins 1-2 & 3-4 plugged 0-10.0V → J1: pins 1-2 plugged in, 3-4 open Box contents: 5 × Current to Voltage Converter Module (0/4-20mA to 0-3.3V/5V/10V)
Product Features
- High Precision Signal Conversion - The current transformer converts standard current signals (0-20mA / 4-20mA) into voltage signals (0-3.3V / 0-5V / 0-10V) - perfectly suitable for microcontrollers or PLC inputs. Excellent linearity (0.1% F.S.) and low temperature drift for precise data processing.
- Wide Voltage Range: The 0/4-20ma to 0-3.3V current to voltage module supports a supply voltage of 7V to 36V DC, making it directly compatible with typical 12V/24V industrial power sources - no additional power supply required.
- Easy Range Selection- The current to voltage module output voltage via DIP switch freely selectable (0-3.3V/5V/10V), no external configuration required. Ideal for fast start-up with Arduino, ST-M32 or PLC analog modules.
- Industrial grade design: the current transformer robust aluminium alloy housing with epoxy resin casting for use in harsh environments. The current transformer operating temperature range: -40C to +85C. Resistant to moisture, dust and vibration.
- Precision resistors - The analogue current transformer equipped with high-precision colour ring resistors for stable signal output, low temperature drift and excellent performance in industrial continuous operation.
