RS485 interface。

2   Other instructions

2.1   Power supply

AC voltage provides two isolated outputs after through the switching power supply, one way is 3.3V provides to the measurement system, the other way is 5V provides to 485 communication circuits and external circuits.

485 communication interface power is(+5 V),current output capability is 100mA

2.2   Working temperature

-20’C ~ +60’C
