NOTE (1) The isolation of the electronic module is 500 Vac RMS between the electronics power by the TM5 to TM7 bus and those powered by 24 Vdc I/O power segment connected to the module. In practice, the 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.
