YOKOGAWA VJQ8-017-1AN0R220 | Pulse/Analog Isolator, 4-20mA, 220Ω
YOKOGAWA VJQ8-017-1AN0R220 signal conditioner. Converts frequency/pulse to 4-20mA, 15-30V DC power, 220Ω shunt resistor, 76x29.5x124.5mm.
Product Overview
The YOKOGAWA VJQ8-017-1AN0R220 is a microprocessor-based frequency/pulse to analog converter from the JUXTA VJ series. It features single-channel isolation and converts a frequency or pulse input into a standard 4-20 mA DC analog output. This model is powered by 15-30V DC and includes a built-in 220 Ω shunt resistor (denoted by /R220) for current loop applications. Its compact, plug-in design is used for signal conditioning and isolation in process control systems.
