Siemens TALON TXM1.16D - Universal I;O Modules (TXM1.8 U and TXM1.8 U-ML); Supply Terminal Connections

TX-I/O Modules
Universal I/O Modules (TXM1.8U and TXM1.8U-ML)
The TXM1.8U and TXM1.8U-ML universal I/O modules provide 8 points, which can be
individually software configured as digital input, analog input, or analog output to best
meet the specific application needs.

All Universal I/O modules provide:
 AC supply voltage for peripheral devices, such as valves and actuators.
 Green LED status per I/O point that varies in intensity according to the voltage and
current (directly proportional).
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.
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
