Hello everybody here,
I have flow meter, and it has single 4-20 ma. I want to connect this flow meter to RTU. This mean to using one signal repeater which has 4-20 ma as output (2 port) and at least on relay with contact (NO&NC) ( digital output) my questions are:
1- could anyone help me and give me the website of this repeater
2- if i get this repeater, how can i using the relays contacts as accumulator counter for this flow meter to able to send the counter’s information to RTU.
I do not think there's such a device anywhere. You must use something else and implement it. I guess you are in China. There are PLCs that can easily perform the functions you want and more. I know one chinese brand that has the modules you need to make this work. Please e-mail me to firstname.lastname@example.org for more information.
