VJH1 Isolated Single & Dual Output Isolator
Brand: Yokogawa Electric CorporationThe VJH1 is a compact, plug-in type isolator that converts DC current or DC voltage signals into isolated DC current or DC voltage signals.
Features- With OOP: VJH1/C (Option code /C) When the load circuit opens (OOP: output open), input resistance increases rapidly to 48 kΩ or more so as to detect the open state through the input device.
- With OOP (HART communication): VJH1/HC (Option code /HC) In addition to the load circuit open (OOP) detection function, HART communication signals are relayed bidirectionally with the field device and host device isolated.
