- Impedance conversion for parallel acquisition by multiple receiving instruments
⚙️ Selection & 교체 정보
Same series DC powered variant: W2YV-AAA-R2 (DC11~27V supply)
국내 대안: Yutong, Chenzhu, Wanxun and other 1-in-2-out 4-20mA isolators (compare isolation rating, accuracy and temperature drift)
메모: The two current outputs have different maximum load limits. OUT2 max load is only 350Ω. Use OUT1 for high-load applications.
📌 Troubleshooting Guide
- Inaccurate output: Recalibrate ZERO/SPAN on front panel; check 250Ω matching resistor on input loop
- 출력 신호 없음: Verify AC supply 85~264V; check tightness of M3 terminal screws
- 신호 드리프트: Check earthing; ensure input side ground is separated from PLC ground. The isolator is used to break common ground.
- Excessive voltage drop under load: Connect the load to OUT1 channel (OUT1 has higher load capacity)

W2VABS: Absolute value signal converter
W2RS: RTD resistance temperature detector isolator
W2YV is only for DC mA/V signal 1-in-2-out isolation and distribution. For temperature measurement or arithmetic functions, select other W2 series models above.
⚠️ Important Selection Notes
- Mixed output (one current + one voltage): Place current signal on OUT1. OUT1 has higher load capacity (750Ω vs 350Ω of OUT2)
- Coated versions C01 are recommended for high-humidity and chemical cabinet environments
- Side-by-side dense DIN installation; no heat dissipation gap required, which is the key advantage of this series

W2YV‑AAA‑M Input Signal Description
For model W2YV-AAA-M specifically: Input is fixed as DC 4~20mA (1st character A), input resistance 250Ω
All Optional Input Types of W2YV Series (1st character in model code)
- 에이: DC 4~20mA (현재 입력)
Input resistance: 250오
This is the input specification of your W2YV-AAA-M
- 6: DC 1~5V (전압 입력)
Input impedance ≥1MΩ, high-impedance voltage acquisition
⚠️ 중요: W2YV series only has these two factory fixed input ranges. It is NOT programmable. It cannot be modified on-site for 0-10V, 0-20엄마, thermocouple or RTD signals. If temperature measurement or multi-range programmable function is required, select other W2 series models such as W2XF.
Brief Comparison
| 암호 | 신호 유형 | 입력 임피던스 |
| 에이 | DC 4~20mA | 250오 |
| 6 | DC 1~5V | ≥1MΩ |
보충
The input range of W2YV is locked at factory by model coding. It cannot be changed by hardware jumpers on site. Only A (4~20mA) 또는 6 (1~5V) can be selected during ordering.
