No.10The DC24V Analog Signal Isolator filters out interference and delivers clean, isolated analog signals between field devices and control systems. It comes in 1 In 1 Out and 2 In 2 Out versions and supports 4-20mA, 0-10mA and 0-5V inputs with 4-20mA, 0-10V and 0-5V outputs. Built on optical isolation technology with optocoupler isolation, a PCB transformer and a high-speed computing chip, it gives ±0.1% F.S accuracy, a ≤0.01s response time and ≥1500V AC dielectric strength. It runs from DC 18-32V and draws only 0.5W. It also offers PWR/ALM fault self-diagnosis, USB online calibration and a thin and light design.

The DC24V Analog Signal Isolator filters out interference and isolates analog signals between field devices and control systems. It protects connected equipment and keeps signal transmission clean and accurate. The isolator comes in a 1 In 1 Out configuration and a 2 In 2 Out configuration, with a range of input and output signal combinations:
| Channels | Input Signal | Output Signal |
|---|---|---|
| 1 In 1 Out | 4-20mA | 4-20mA |
| 1 In 1 Out | 4-20mA | 0-10V |
| 1 In 1 Out | 4-20mA | 0-5V |
| 1 In 1 Out | 0-10mA | 4-20mA |
| 1 In 1 Out | 0-10mA | 0-10V |
| 1 In 1 Out | 0-10mA | 0-5V |
| 1 In 1 Out | 0-5V | 0-5V |
| 1 In 1 Out | 0-5V | 4-20mA |
| 1 In 1 Out | 0-5V | 0-10V |
| 2 In 2 Out | 0-5V | 0-5V |
The isolator is built on optical isolation technology. It combines optocoupler isolation, a PCB transformer and a high-speed computing chip to improve anti-interference ability and keep the signal stable. It achieves an isolated transmission accuracy of ±0.1% F.S, a temperature drift of 40ppm/°C and a response time of ≤0.01s, with an output ripple of ≤5mVrms (250Ω load).
For electrical safety, it provides a dielectric strength of ≥1500V AC and an insulation resistance of ≥100MΩ. Its electromagnetic compatibility conforms to IEC61326-3. On the current-input versions, the input can come from a current source, a 2-wire transmitter or a 3-wire transmitter.
The module runs from a DC 18-32V power supply (24V DC) and has ultra-low power consumption of only 0.5W, so it generates little heat and dissipates heat quickly.
To make installation and debugging efficient, the isolator has fault self-diagnosis with PWR and ALM indicator lights:
- The ALM light flashes automatically when the input signal fails.
- The ALM light stays on when the input signal is overloaded.
A PRO port supports USB online calibration. The thin and light housing measures 12.5 x 110 x 118.9 mm for the 1-channel version and 17.7 x 110 x 118.9 mm for the 2-channel version, which saves cabinet space. The product integrates German technology, carries CE and FC markings and can be customized for special needs.
