User Manual
(1) The isolators adopt knock-down terminals.
(2) The wires are single or multiple cables with cross-section of 0.5
2 2.
mm ~2.5mm
(3) A length of 8mm bared wire is locked by the M3 bolt. As shown in
figure.
Mount the module on a 35mm DIN rail
(1) Make the upside of the isolator to the rail;
(2) Push the downside of the isolator towards the rail.
(1) Use a screwdriver (edge length≤6mm）insert the metal lock which at
the downside of the isolator;
(2) Push the screwdriver upwards, and pull the metal lock downwards;
(3) Take out the isolator from the rail.
(1)Every product has been tested strictly before delivery. If users find
any abnormality, please contact the nearest agent or our company.
(2) In 5 years from delivery date, if the product performs abnormally
under normal use conditions, we will repair it for free.

Summarize
Specification
Number of channels: 1/2 (CZ3074)
2 (CZ3079.TC)
Supply voltage: 20~35V DC
Current consumption: (at 24V DC supply, 20mA output)≤55mA
Input: See “input signal and range scope list” as below
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.TC input, transfer accuracy not contain cold junction compensation
error;Every increase in compensation wire 100Ω, cold end error increases 0.2 ℃;
3. TC type B input, the lower limits of temperature range must be greater
than 680℃, to meet the accuracy specifications.
4. mV signal has to be customized.
Output: Current: 0/4~20mA; Load resistance: RL≤300Ω
Voltage: 0/1~5V; Load resistance: RL≥20kΩ
(Note: output current: load resistance: , Current consumption: ,
need be customized)
Alarm indication:
Lower than range, LED YELLOW flashing, output current ≈ 3.8mA
Higher than range, LED RED flashing, output current ≈ 20.8mA
Breakage, LED YELLOW and RED flashing alternately, output current ≈ 20.8mA
Breakage, LED YELLOW and RED flashing alternately, output current ≈
20.8mA
(Note: breakage alarm current<4mA or other special requirements, need to
be customized)
Temperature drift: 0.01%F.S./℃
Cold junction compensation: ±1℃(Compensation range: -20℃~+60℃)
Response time: Reach 90% of final value in 1s
Power supply protection:
Protect the product from reverse supply voltage destroy
Electromagnetic compatibility: According to IEC 61326-1(GB/T 18268)
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.150g
Suitable IS apparatus: Thermocouple, mV signal
RL≤550Ω ≤75mA

(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%
Thermocouple type isolator, convert thermocouple, mV signal into 0/4~20mA
current signal or 0/1~ 5V voltage signal and output isolatedly. It is intelligent and
has cold junction compensation function, TC graduation and range can be
configured through computer. This product needs an independent power supply.
Input circuit, output circuit and power supply are each galvanically isolated.
