TX-I/O Modules
Supply Terminal Connections
NOTE:
The neutral of analog inputs and outputs must always be connected to the
terminal associated with that I/O input.
All supply terminals are connected in the I/O module, not in the terminal base.
The neutral of a digital input (on Digital Input, Universal and Super Universal
modules) can be connected to any neutral terminal on the same module. Several
digital inputs can also share a neutral terminal on the same module.
DC Output (Field Supply)
The following information applies to terminals 3, 11, 20, and 28.
Nominal voltage (derived in the module from
the module supply voltage)
24 Vdc
Admissable current per module Max. 200 mA (total for all four terminals)
AC/DC Output (Field Supply)
The following information applies to terminals 7, 15, 24, and 32.
Voltage AC/DC 12 to 24 V
Admissable current per module Max. 4 A (total for all four terminals)
Fuse 4A, in TX-I/O Power Supply or
Bus Connection Module
Active Input and Output Support
CAUTION
Active inputs and output are permitted on the same module when connected
sensors are powered from that module.
When sensors are externally powered, active inputs and outputs should be on
separate modules.
NOTE:
The neutral of analog inputs and outputs must always be connected to the
terminal associated with that I/O input.
Active input and output support includes the following:
Analog input and output (0-10 Vdc)
Analog input current 4-20 mA
Analog output current 4-20 mA (four current outputs maximum per module on
Points 5 through 8)
24 Vdc supply voltage for sensors at a maximum of 200 mA per module.
