Connection mode

a)Terminal 1 and terminal 2 are 24V power supply positive and negative respectively, and the circuit board has anti-reverse connection function.

b)The thermal resistance connection supports two - wire system and three - wire system. The connection mode is as shown in the figure above. The solid wire is the lead wire of the sensor, and the dotted wire is the short wire, which requires the user to connect with the short wire by himself (the factory can also connect the short wire internally according to the customer's needs).

c)The positive pole of thermocouple is connected to the no. 3 terminal, and the negative pole is connected to the no. 4 terminal.
