TM241C••24T Regular Transistor Outputs Source Wiring Diagram
The following figure shows the source wiring (positive logic) of the outputs:
* Type T fuse
(1) The V1+ and V2+ terminals are not connected internally.
(2) The V1– and V2– terminals are not connected internally.
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Ensure that the physical wiring respects the connections indicated in the wiring diagram, and, in particular, that both V•+ and V•- are connected, and that only 24Vdc is connected to the V•+ terminal(s) and only 0Vdc is connected to the V•- terminal(s). |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
