hi 

 

i want to know can i use all analog input 4-20ma of jz20- r16 

 

thanks

Hello,

 

On the JZ20-R16, there are 4 analog inputs.  Two inputs may only be used for 0-20/4-20mA signals, and there other two may only be used for 0-10VDC signals.

 

Do you need all 4 to be for 4-20mA signals?

i need 1 0-10v 3 4-20ma 

 

thanks for replay

Would the M91-2-R6C work for you?

 

-6 Digital Inputs (1 HSI)

-6 Analog Inputs (2 are 0-10VDC/4-20mA, 4 are 4-20mA)

-6 Relay Outputs

i know but i want to learn jz20-r16 provide  my need

 

thanks

Just use the 4-20ma sensor devices on one of the 0-10Vdc inputs by placing a 250 Ohm resistor between PLC terminal 4 (i6-7) and terminal 8 or 9 (i6 or i7)(whichever one you chose to put the 4-20 device on).  This will give you a 1-5 volt input from a 4-20ma output device.  Or a 500 ohm resistor will give you a 2-10v signal from a 4-20ma device.  you would scale the input the same way you would a regular 4-20ma device if you use the 500 ohm resistor.

 

Thanks
