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
Thermocouple input isolator, transfers TC, mV signal into 0/4~20mA or
0/1~5V and output isolatedly. It has automatic cold junction compensation
function. It is intelligent and could be configured with parameters such as the
graduation of thermocouple and the scope of range through computer. This
product should be supplied power independently. Input circuit, output circuit
and power supply are each galvanically isolated.
Specification
Number of channels: 1
Supply voltage: 20~35V DC
Current consumption: (at 24V DC supply, 20mA output)≤35mA
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, flashing, output current ≈ 3.8mA
Higher than range, LED H flashing, output current ≈ 20.8mA
Breakage, both L and H are flashing , 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 error : ±1℃(-20℃~+60℃)
Response time: Reach 90% of final value in 1s
Power supply protection:
Protect the product from reverse supply voltge 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.100g
Suitable IS apparatus: TC and mV signal sensor
RL≤550Ω ≤
