Parameters of Remote IO Module ZHT4400
ZHT4400 is a serial port control module that provides 4 DI, 4 DO and a RS485 interface, support the standard Modbus RTU protocol, support dry wet node detection, support relay delay shut down after opening, we provide comprehensive technical supports. It can be widely used in pump control, access control monitoring, lighting control, such as valve monitor application scenario.
Logic Follow Setting
Function introduction: After the device is powered off, it will memorize the state before the power off. When the device is powered on again, the device will restore the state before the power off.
Note: This function is turned off by default.
Setting method: select the required follow mode at the logic follow setting, and the setting is successful after saving.
Function introduction: Reset the device to the initial state.
Setting method: Turn all the DIP switches to OFF, that is, when the address is 31, the setting is reset. Wait 3 seconds and then turn the DIP switches back to reset successfully.
