WC0A Output Isolator
Brand: Yokogawa
The WC0A is a compact, front terminal connection type isolator that converts 4-20 mA DC signals into isolated 4-20 mA DC or 10-50 mA DC signals.
Features- When a load circuit opens, input resistance increases rapidly to 32 KiloOhms or more to detect the open state through the input device
- 2,000 Vac withstand voltage specifications are available upon requests
