VJT6 Single & Dual Output Thermocouple Converter

Brand: Yokogawa Electric Corporation

The VJT6 is a compact, plug-in type thermocouple converter that is connected to an IEC/JIS-standard thermocouple (TC), such as a Type K, T, E, J, R, S, B or N thermocouples to convert temperature signals into isolated DC current or DC voltage signals.
