产品简介

YOKOGAWA Model VJU7 Universal Temperature Converter
(Isolated Single-output and Isolated Dual-output Types)
This plug-in type universal temperature converter converts input signal (thermocouple, RTD or mV signal) into isolated DC voltage signal or DC current signal.

产品详细信息

YOKOGAWA Model VJU7 Universal Temperature Converter

• Universal input enables selection of input type (thermo-couple, RTD, mV signal) and of measuring ranges within specifications.

• DC voltage signal, DC current signal, communication output (RS485), or alarm output (2 relay contacts) is selectable as output-2.

• Change of input types / input ranges/burnout action, and I/O monitoring etc。 can be done through Handy Terminal (JHT200 etc。)。

Input
Input Signal Type:
Thermocouple (ITS-90): Type K, T, E, J, R, S, B, N,W3 (see Note 1), W5 (see Note 2)
Note 1: W3 is the abbreviation of W97Re3-W75Re25 (tungsten97 % rhenium 3 % - tungsten75 % rhenium25 %) ASTM E988 Standard
Note 2: W5 is the abbreviation of W95Re5-W74Re26 (tungsten95 % rhenium 5 % - tungsten74 % rhenium 26 %) ASTM E988 Standard 
RTD
: Pt100 (ITS-90), JPt100 (JIS’89)
Pt50 � (JIS’81), Pt100 (IPTS-68)
Pt100 (ITS-90): R0=100 �, R100/R0=1.3851
JPt100 (JIS’89): R0=100 �, R100/R0=1.3850
Pt100 � (IPTS-68) : R0=100 �, R100/R0=1.3916
mV signal : Can be set within -10 to 100 mV

Measuring Span: 3 mV or more (thermocouple, mV signal)
10 �C or more (RTD)
Input Resistance: 1 M� (when power on), 4 k� (when
power off) when thermocouple, mV input
Input External Resistance:
Thermocouple, mV signal: 500 � or less
However, when combination with BARD200, it is the value connectable as
external resistance besides internal resis-tance.
RTD:
Input span (�C) � 0.4 � or less / wire or 10� or less, whichever smaller
However, when combination with BARD300, it is the value connectable as external
resistance besides internal resistance.
RTD Detective Current: About 0.5 mA
Permissible Applicable Voltage: �4 V DC or less
