How to mount?
Fault situation:no output or wrong output
Reasons possible:
(1) The wrong measure range leads to PLC calculation wrong, the measure range please refer to the technology in the first part.
(2) Wrong connection mode or wrong connection order.
(3) Wrong power voltage (the type 0-10V is all power supplied in 24V).
(4) Over distance between transducer and collector leads to signal disorder.
(5) PLC collection point is damage.
(6) Device is broken.
Application
Our temperature transmitter can be widely used in greenhouse, outddoor, machine room, hospital, etc. Because its cheap price, good performance and 2years warranty, this transmitter is very popular from home and abroad.
