Hi there,
I am a bit new to PLCs.
I have a Twido PLC and I have an Expansion module with 2 Analog Inputs (0 - 10V, 4 - 20mA). The model is TWDAM12HT.
I want to inject a 0-10V value into one of its inputs. However, I cannot seem to get the value in the input. I made a very simple program that will turn off a DO point on my PLC when the value of the AI is non-ZERO.
I connected a 5V input in the AI but the DO point LED is still on. Meaning, the AI is still zero. Moreover, in the Twidosoft program, it indicates that it is still zero.
Right now, I doubt if my hardware connection is correct. The module has 3 terminals with label 24VDC. It has a positive, negative and a ground connection. I dont have the manual for this so I do not know whether I need to put a 24V power supply on these ports.
Perhaps there are guys in the forum who have worked with this model TWDAMI12HT module.
Any help would be appreciated.
Thanks,
