DC0 Output Isolator
Brand: Yokogawa Electric Corporation
The DC0, a nest-mounting type DCS-supported isolator, receives 4 to 20 mA DC signals from DCS, and converts them into 4 to 20 mA DC or 10 to 50 mA DC current 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
- Recommended arrester: AR-HA
