Electrical connection
Fig. 6: Electrical connection of the compact thermometer (viewed from above)
– M12 plug, 4-pin
Pin 1: Power supply 10 to 35 V DC; Current output 4 to 20 mA
Pin 2: PC configuration cable connection
Pin 3: Power supply 0 V DC; Current output 4 to 20 mA
Pin 4: PC configuration cable connection
The connection cable 5 m is for the 4..20 mA signal and will be connected with pin 1
and 3 as shown in the picture. The pins 2 and 4 are for the communication with the
computer. If you look on the communication adapter then you see that there are two
male pins that are making connection to the two shortend metal pins 2 and 4. By the
way the supply for the TSM470 for the communication is done by the computer
interface.
