Hi dear H_H Thanks for your informative post.Please check the attachment in which 2 DO are connected via 2 diodes to a relay.Is it possible to implement such configuration with SIEMENS modules or external diodes should be bought?

Hello hdhosseini, Siemens has some digital output modules with internal diodes for parallel operation. The attached PDF has been extracted from S7-400H manual. You can also find which modules have internal diodes when you look at the detailed specification in S7-300 module data. Best regards. H-H AttachmentRED-DQ.pdf (286 Downloads) |
