Abstract
An explosion proof electrical feedthrough assembly is provided in a process variable transmitter which has a sensor sensing a process variable and providing a sensor output signal indicative of the process variable. The transmitter also includes a processing circuit coupled to the sensor to receive the sensor output signal and provide a transmitter output signal based on the sensor output signal. The feedthrough assembly includes a terminal block which is coupled to the processing circuit and includes power supply terminal connectors and communication signal connectors. The communication signal connectors are arranged generally radially about the power supply terminal connectors.
