📋 Core Technical Specifications

🎯 Aplicações Típicas

1. Eliminate ground loop interference between CLP e transmitters
2. Distribute one 4~20mA measurement signal to PLC + recorder / indicator (1-input 2-output signal splitting)
3. Provide galvanic isolation between field transmitters and control room systems to protect AI modules
4. Impedance conversion for parallel acquisition by multiple receiving instruments

⚙️ Selection & Informações de substituição

Same series DC powered variant: W2YV-AAA-R2 (DC11~27V supply)

Alternativas domésticas: Yutong, Chenzhu, Wanxun and other 1-in-2-out 4-20mA isolators (compare isolation rating, accuracy and temperature drift)

Observação: The two current outputs have different maximum load limits. OUT2 max load is only 350Ω. Use OUT1 for high-load applications.

📌 Troubleshooting Guide

1. Inaccurate output: Recalibrate ZERO/SPAN on front panel; check 250Ω matching resistor on input loop
2. Nenhum sinal de saída: Verify AC supply 85~264V; check tightness of M3 terminal screws
3. Desvio de sinal: Check earthing; ensure input side ground is separated from PLC ground. The isolator is used to break common ground.
4. Excessive voltage drop under load: Connect the load to OUT1 channel (OUT1 has higher load capacity)

📌 Other W2 Family Models (Same DIN rail housing as W2 series)

W2XF: Arithmetic signal conditioner (addition / subtraction calculation)

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

1. Saída mista (one current + one voltage): Place current signal on OUT1. OUT1 has higher load capacity (750Ω vs 350Ω of OUT2)
2. Coated versions C01 are recommended for high-humidity and chemical cabinet environments
3. 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)

1. UM: DC 4~20mA (Entrada atual)

Input resistance: 250Oh

This is the input specification of your W2YV-AAA-M

2. 6: DC 1~5V (Entrada de Tensão)

Input impedance ≥1MΩ, high-impedance voltage acquisition

⚠️ Importante: W2YV series only has these two factory fixed input ranges. It is NOT programmable. It cannot be modified on-site for 0-10V, 0-20mA, thermocouple or RTD signals. If temperature measurement or multi-range programmable function is required, select other W2 series models such as W2XF.

Brief Comparison

Suplemento

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) ou 6 (1~5V) can be selected during ordering.
