I’d like to ask the experts: what kind of signal travels between the counter and the display panel?

Reply #22016-12-03

Generally, 4-20 ma is more common

The signal from the display panel to the PLC is an electrical current signal; the signal from the primary meter to the display panel should not be one

Reply #42016-12-03

There are all kinds of signals: voltage, current, resistance

Generally, it’s not really a current signal; I’ve encountered 232 signals the most. There are also those that use 485.
