Note: 1. Power bus power supply is an optional function.Users need to specify the power supply method when ordering.
2.When using a three-wire thermal resistor input,try to ensure that the three wires are of equal length.
3.When using a two-wire thermal resistor input,the safety barrier terminals 4 and 2 must be short-circuited.
