hello everybody.
MY plc is cpm1 20cdr-a(omron).
i m using this plc and i m facing problems related to:
1- i have moisture sensor(analog input) that on/off a valve(digital output)
so how can i do? is there thresholding inside plc so that it convert it automatically? or is there any way to threshold the analog input to make it digital using cx programmer?
2- my plc output capacity is 24vdc and 0.3A. i want to on/off two 12vdc valves and 12vdc pump(0.3A). i m thinking the plc output(24vdc) should be regulated to 12vdc. m i right?
or plc output can't on/off motor? if it cant then i need to use a relay switch.
3-a plc output come with only one wire and valve need to wire(+ and -) so is plc output wire has polarities?
any help will be appreciated.
best regard
