1、 The function and working principle of passive signal isolators:

The main function of a passive signal isolator is to solve the interference problem caused by common ground between devices. Its working principle is to supply power through the input circuit to achieve signal isolation, ensuring absolute independence between the converted signal, power supply, and ground. ‌

2、 Technical parameters of LYW series passive signal isolators:

1. Input signal: 4-20mA @ Input terminal power supply voltage ≤ 30VDCB

2. Output signal: 1-20mA

3. Output load: ≤ 2500 when 4-20mA

4. Basic error: ± 0.2% FS (at 2500 load)

5. Input signal load capacity:>500

6. Temperature drift:<0.01% ES/℃

7. Insulation resistance: ≥ 100M0/500VDC between input and output

8. Insulation strength: 1000VAC/min

9. Power consumption:<1W

10. Working environment: ambient temperature of 0-50 ℃; Relative humidity ≤ 85% RH (avoid strong corrosive gases)

11. Installation method: Rear mounted card (DIN35 rail)
