📋 Grundlegende technische Spezifikationen

🎯 Typical Applications

1. Eliminate ground loop interference between SPS Und Sender
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 & Ersatzinformationen

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

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

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

📌 Troubleshooting Guide

1. Ungenaue Ausgabe: Recalibrate ZERO/SPAN on front panel; check 250Ω matching resistor on input loop
2. Kein Ausgangssignal: Verify AC supply 85~264V; check tightness of M3 terminal screws
3. Signaldrift: 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)

W2YV ist nur für die 1-in-2-out-Isolierung und -Verteilung von DC-mA/V-Signalen vorgesehen. Für Temperaturmessungen oder Rechenfunktionen, Wählen Sie oben weitere Modelle der W2-Serie aus.

⚠️ Wichtige Auswahlhinweise

1. Gemischte Ausgabe (ein Strom + eine Spannung): Legen Sie das aktuelle Signal an OUT1. OUT1 has higher load capacity (750Ω vs. 350Ω von OUT2)
2. Beschichtete Versionen C01 werden für Umgebungen mit hoher Luftfeuchtigkeit und Chemikalienschränken empfohlen
3. Dichte DIN-Installation nebeneinander; kein Wärmeableitungsspalt erforderlich, Das ist der entscheidende Vorteil dieser Serie

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. A: DC 4~20mA (Aktueller Eingang)

Input resistance: 250Oh

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

2. 6: DC 1~5V (Spannungseingang)

Input impedance ≥1MΩ, high-impedance voltage acquisition

⚠️ Wichtig: 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

Ergänzen

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