Communicate function(Optional): RS-485 communication interface (MODBUS protocol partially compatible), the value corresponding to the4-20mA current output can be arbitrarily set, photoelectric isolation4-20mA current output
The function of setting hysteresis random, avoiding the frequent action of switch relay, has the function of setting switch off and closing.
Watchdog function: make sure the meter doesn't crash.
Power off protects > 10 years.
