A-B 1756-EWEB

Description

1756-EWEB description The working principle of the circuit is that when the voltage of the two input power supplies is the same (the difference is less than 100mV), G2 controls the two MOSFETs to be switched on at the same time, so that both inputs provide current to the load at the same time. When the input supply voltage is different, the output supply voltage can be higher than an input supply voltage, then the LTC4416 prevents the output from backing up to the input current. This is because the chip is always monitoring the voltage difference between the input and output. When the voltage on the output side is 25mV higher than the voltage on the input side, the chip controls G1 or G2 to turn off the MOSFET to prevent the current from reversing the current. Other control chips are similar in preventing backflow.

How to control the AB touch screen display through PLC?
Open the ME software to find the global connection, look for the remote display number in the Display TAB, fill in the PLC marker, and assign a value to the marker in the PLC.
For example, your plc label is disynumber, assigned 12, and the touch screen opens 12. 1756-EWEB Description
