Poljachina Posted June 14, 2021 Report Share Posted June 14, 2021 Hello all. This is the first time I am working with a Unitronics PLC and would need some help regarding the wiring and configuration of the on-board analog input. I have an INOR 2 wire transmiter that will transform a PT1000 temp value to 4-20mA signal that the PLC will read(see attached picture1). So I set the jumper JP8 and JP9 to B so that analog input #0 is set to Current. Also configured analog input 0 to 4-20mA in VisiLogic. So I tried to wire the transmitter like it is drawn in the manual of the Samba PLC (manual page 8). Inor terminal 6 to +24 V DC, Inor terminal 7 to analog input of the Samba PLC (terminal 9). But I don't get any value from the analog input. Have I missed something in the configuration of the PLC or most likely the wiring is not correct. Any info would be great. Thank you in advanced. Cheers Aleix. Quote Link to comment Share on other sites More sharing options...
