VJA1 Isolated Single & Dual Output Distributor
Brand: Yokogawa Electric CorporationThe VJA1 is a compact, plug-in type distributor that is used in combination with a two-wire type transmitter to convert the transmitter’s 4-20 mA DC signals into isolated DC current or DC voltage signals.
Features- HART communication: VJA1/H (option code /H) Bi-directional relay of HART communication signals is possible while the field devices and the higher-level device are isolated from each other.
- Supports BARD-800.
