1 The isolation of the block is 500 Vac RMS between the electronics powered by the TM7 power bus and those powered by the 24 Vdc I/O power segment connected to the block. In practice, there is a bridge between the TM7 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.
