Use TU810 for DO828 16-channel relay module
I have a test/training Environment with some DI810/DO810 on TU810 Termination Units.
Now i got a DO828 Module for testing but i am missing the TU851 required to connect it.
Is it electrically possible to connect the DO828 to a TU810 for testing purpose (24 VDC) and what would be the pin-out for this Situation?
Hello, below are the connection diagrams for both TU810 and TU851 (you may be also look on them). Unfortunately there are no pin numbers for the connector between TU and the module - it is named as Process Connector.
I can't judge if you can use TU810 for testing. DO828 "produces" only dry contacts, so MAY BE it could not be damaged in case you place it on TU810 (no power supply requirements). May be you could measure pin by pin this connector (process connector) and try - but for me seems too dificult.
Anyhow, in the manual is written to use DO828 with TU851 only.
I think that is the only right way.
