Working Functions of Modbus TCP IO Module

Working Principle

Remote control equipment, unlimited distance,

such as controlling Shanghai equipment in Beijing, monitoring Xiamen equipment status.

In this mode, every time the relay is operated, the relay will remain in the state of recovery for a certain time after turning over.

Flash mode: for each operation of the relay, the relay will close for a certain time and then automatically open
Flash off mode: for each operation of the relay, the relay will open for a certain time and then close automatically
Actual time = set number * 0.1, in seconds

DI^&DO&AI&AO of Modbus TCP IO Module

◆Each output is independent and can be connected with different load equipment, such as 220 V electric lamp and 24 V solenoid valve
◆The maximum contact capacity is 250VAC, 10a / 30VDC, 10a
◆The service life is 10W times
