Summarize Operation Conditions
(1). The air should not contain any medium corrupting the coat of
chrome,nickel and silver.Moreover,violent quiver and impact or any cause
of electromagnetic induction (such as big current or spark,etc.)must be
avoided when using.
(2). Operating temperature: -20℃~+60℃
(3). Storage temperature: -40℃~+80℃
(4). Relative humidity: 10%~90%

Note:
1.3-wire RTD system input, as far as possible to ensure equal three wire
resistance value.
2.terminals 6 and 7 must be connected when 2-wire RTD inputs.
Specification
Number of channel: 1
Supply voltage: 9~30V DC
Input: “Input signal and range list”
Note: 1.”%” of output accuracy is relative to the setting range, should
take a bigger of relative error and absolute error as the output accuracy
in application.
2. RTD input, allow max wire resistance 50Ω(3-wire);
3. TC input, transfer accuracy not contain cold junction compens-
ation error;Every increase in compensation wire 100Ω, cold end error
increases 0.2 ℃;
4. RTD type B input, the lower limits of temperature range must be
greater than 680℃, to meet the accuracy specifications.
5. mV signal has to be customized.
Output: Current: 0/4~20mA; Load resistance: RL≤
Alarm indication:
Lower limit overflow alarm, output current ≈3.8mA;
Upper limit overflow and breakage alarm, output current ≈20.8mA
(Notes: breakage alarm current<4mA or other special requirements, be
customized)
Temperature drift: 0.01%F.S./℃
Cold junction compensation: ±1℃(Compensation range: -20℃~+60℃)
Intensive installation: ±3℃
Response time: Reach 90% of final value in 1s
Power supply protection:
Protect the barrier form reverse supply voltge destroy
Electromagnetic compatibility:According to GB/T 18268(IEC 61326-1)
Dielectric strength:
1500V AC;1minute(among power supply input and output )
Insulation resistance:
≥100MΩ;500V DC(among power supply,input,output and the shell)
Weight: Approx.45g
Suitable is apparatus:
2-/3-wire thermal resistance, thermal couple and mV signal
(Ue-9)/0.021
Loop-powered isolator, converts thermal resistance, thermal couple,
and mV signal field into 4~20mA current for driving load. It has sensor
breakage alarm indicator function. TC input has cold junction
compensation function. It is intelligent, indexing number of TC and range
can be configured through computer.
