TX-I/O Power Supply and Bus Modules
Supply Terminal Connections
24 Vac supply terminals are fused (replaceable) for Class 2 (24 Vac at 50/60 Hz)
through the TX-I/O Power Supply.
24 Vdc supply terminals are connected in the I/O module, not in the terminal base.
24 Vdc is supplied and overload protected in the TX-I/O Power Supply.
