CPU 314C-2DP, Analog Output

3/17/2008 9:46 AM	Rate (0)
Hunky Posts: 82 Rating: (6)	Dear All, I am using CPU 314C-2DP and it is having inbuild 2 Analog outputs. I has configured them as 0-10V DC. But i am not getting 10V DC from it. It is giving max. 6.5V only. I have connected as per the wiring diagram (AO1- Between terminals 16 & 20 and AO2- Between terminal 18 & 20). I am unable to understand the problem. Please help me to sort out. Thanks in advance. Regards PLC Engineer

	Best regards, Darius
