Hi,
i'm planning on building a AIO electric beer brewer with about 80 liter capacity. i was thinking of using an micro 850 i have for controlling mashing stages, circulation pumps, temp controll.
i was thinking of using two 1600w heating elements and a 24vDC pump.
My I/O options are 14/10 (micro 850 lc-50 24qwb) only relay outputs, an analog input plugin with 4 inputs and an analog output plug in with 2 outputs.
since i cannot run any SSR directly from the PLC because of the relay outputs, what can i ad to best control the heating elements? it requires accurate temp controlling within +- 0,5 degree.
Also, what would be the best solutuion to controlling the pump?
i have an 7" TFT HMI from AB i was planning on using for set values, temp readings, timers etc. and ofc some awesome graphic simulation of the system.
