hi Krriipc My huge doubt is here. as per the DSC_1782[1].jpg, i have connected Terminals 1 and 2 for '+' and '-' respectively. But I think what I have made is not in accordance to the manual on pg no 3 there is "Connection to a PLC/Recorder, separate supply". But if i make this as per "Connection to a PLC/Recorder, separate supply", The meter is not getting "ON". Also as per Pg no:22 in the attachment, the two wires should be directly connected from the transmitter to the module. I think a lot about "where is the current loop in this?". But dully followed as per the diagram in Pg no:22 Attachments7300_sm331_ai_8x12_bit_getting_started_en-US_en-US.pdf (290 Downloads) |

Hello kalidasan You need to check whether your transmitter is a 2-wire or 4-wire ? The Below attachement will help you understand the difference between the two. In both cases there are only 2 wires connected to the AI Module. In case of 2-wire ( Loop Powered ) the transmitter power is derived from the 4-20mA signal itself. In case of 4-wire, transmitter requires a separate auxiliary supply Hope this helps Cheers Navnag AttachmentDiff between 4-20ma 2Wire 4Wire.pdf (320 Downloads) |

Hello kalidasan YourConnections on the PLC side are perfectly all right ( Hand sketch uploadedby you earlier ) Just for your ready reference, pl see attached the 2-wire wiring diagnam for 6ES7331-7KF02-0AB0 Hope this helps Cheers Navnag Attachment6ES7331-7KF02-0AB0_2W_4W.pdf (337 Downloads) |
