WIRING DIAGRAM
PT100 Wiring Method
No. 11~13 are the first terminal of PT100/PT1000, No. 13~15 are the second terminal of PT100/PT1000, and so on. PT100/PT1000 has one A line and two B lines. Connect the A line of the PT100/PT1000 to the terminal number labeled A, and connect the two B lines to the terminal numbers labeled B and C.
NTC Wiring
No. 12~13 are the terminals of the NTC‘s channel 1, No. 13~14 are the terminals of the NTC’s channel 2, and so on.
Thermocouple Wiring
11~12 is the 1st thermocouple terminal, 11 is connected to V-, 12 is connected to V+, 14~15 is the 2nd thermocouple terminal, 14 is connected to V+, 15 is connected to V-, and so on.
