An apparatus includes multiple circuit paths configured to generate multiple electrical signals to be used to communicate with multiple devices. Each of the circuit paths is configured to use electrical energy from a different one of multiple independent power supplies. The apparatus also includes an I/O terminal configured to be coupled to a common electrical conductor that is coupled to the multiple devices. The I/O terminal is configured to pass the electrical signals to the common electrical conductor. The apparatus is configured to use each of the electrical signals to one of: receive input data from one of the multiple devices or provide output data to one of the multiple devices.

Multi-device connections for input/output (I/O) terminals

A redundancy termination panel includes first and second interfaces configured to be coupled to first and second I/O modules, respectively. The redundancy termination panel also includes a third interface configured to be coupled to a field device. The redundancy termination panel further includes an I/O channel circuit associated with an I/O channel between the I/O modules and the field device. The I/O channel circuit is configured to allow an input current used for receiving data from the field device to be split such that different portions of the input current are sourced by different ones of the I/O modules. The I/O channel circuit is also configured to combine multiple currents driven by different ones of the I/O modules and provide an output current used for sending data to the field device.
