dseligo Posted August 24, 2023 Report Share Posted August 24, 2023 Is it allowed/safe to connect together transistor outputs from two Jazz PLC's (specifically JZ20-J-T18) or must they be separated with diodes? They would be connected to the same relay. In other words, can damage be made to PLC if 24V is applied to output while it is inactive? They are on the same power supply.
