Momentary Switch

I am looking for controlling two channel relays where it moves from NO to Closed and returns back to NO after 1 second. Which model is recommended and which protocol it supports?

you can use KC868-A2 , it's ok for your requirements. support HTTP, MQTT, TCP command and Modbus protocol with RS485.

Does the time control will be in the code ? or on the module by default?
