VJA5 Isolated Single & Dual Output Distributor

Brand: Yokogawa Electric Corporation

The VJA5 is a compact, plug-in type distributor that is used in combination with a two-wire type transmitter to calculate the square root of 4-20 mA DC input signals from the transmitter and then convert them into isolated DC current or DC voltage signals.
