Hello, PLC used:314 DO module: DO 32x24VDC/0.5A Contactor: 3TF 3400-0BB4. Everything was working find with this configuration. Later I had to change the contactor to 3RT20361NB30. Then the DO module was not able to switch ON the contactor and the LED in DO module was flickering. I understood as the DO module is not having enough amps to switch it ON, so later I used an additional relay to switch the new contactor 3RT20361NB30. So my question is where we should look into in both DO module and contactor and understand whether the DO module can trigger the contactor directly or not? I could see coil supply as 24V, where it was same for both the above mentioned contactor, but it wasnt working. Attached the pdf for the contactor for ready reference. Please help to avoid surprises on field. Thank you. ------------------------------------------------------------------------------------------ Attachment3RT20361NB30_datasheet_en (1).pdf (663 Downloads) |
