text: <s>[INST] can multiple 753 safe torque-off modules be connected and maintain the safety function Has anyone cascaded multiple 753 drives thru the 20-750-s safe torque off module. Can this be done ? I have a customer who would like to use 1 safety output to control 16- 753 drives ,he wants to maintain a cat3 rating. Thanks John [/INST] You should be able to parallel the signal from a safety relay output to the 20-750-S modules. The returns would also then be tied together as well. TJ McDermott \\n </s>
