* Note: These analog electronic modules are subject to operating temperature restrictions between 55 and 60 °C (131 and 140 °F). If the ambiant temperature of your installation may exceed 55 °C (131 °F), do not install the TM5SAI•H modules adjacent to other devices capable of dissipating more than 1.15 W. For more information refer to Enclosing the TM5 System. |

1 The isolation of the electronic module is 500 Vac RMS between the electronics powered by the TM5 bus and those powered by 24 Vdc I/O power segment connected to the module. In practice, the TM5 electronic module is installed in the bus base, and there is a bridge between the TM5 power bus and the 24 Vdc I/O power segment. The two power circuits reference the same functional ground (FE) through specific components designed to reduce effects of electromagnetic interference. These components are rated at 30 Vdc or 60 Vdc. This effectively reduces isolation of the entire system from the 500 Vac RMS.
The analog output modules can be configured as voltage outputs, current outputs, or a mix of voltage and current outputs. In the case of a mixed configuration, you must adjust the following de-rating information.
If only one of the outputs in the mix is configured as a current output, use the mean between the current and voltage curves. If more than one output in the mix is configured as a current output, use the current output de-rating curve. Otherwise, use the appropriate de-rating information as follows:
De-rating the voltage output load in a horizontal installation:
1 Invalid area
De-rating the current output load in a horizontal installation:
1 Invalid area
De-rating the voltage output load in a vertical installation:
1 Invalid area
De-rating the current output load in a vertical installation:
1 Invalid area
