Precautions for wiring of RTD & TC Module (
Cables for module input signals should be separate from AC power to prevent the influence
of surge or induction noise occurring from AC.
Select a cable considering the ambient temperature and allowable current. AWG16-28 is
recommended.
If the wiring is too close to a heat-generating device, or directly contacted with oil for long
periods of time, it may cause a short circuit, breakdown, or malfunction.
In the case of wiring together with a high-voltage cable or power line, a malfunction or
breakdown may occur.
Our TC modules are non-isolated between channels and use FG in common.
An FG connection is recommended. In particular, FG reinforcement is strongly
recommended when the measured values fluctuate quickly.
When the TC sensor is connected to multiple sources at the same time, electrical
interference may occur between them. So, it is not recommended to use simultaneous
common connections
If it is necessary to use another company's model, you must connect the FG of our model
with that of the other company's model.
Precautions for test run and repair (
Please do not touch the terminals when the power is on. Doing so could cause an electric
shock or malfunctions.
When cleaning or tightening the screws, turn off the power of the PLC and all other systems.
Failure to do so could cause an electric shock or malfunctions.
Do not charge, disassemble, heat up, short, or solder the battery. Doing so could cause the
battery to heat up, rupture, or ignite, thereby harming the user.
(this is the main cause of abnormal measurements).
