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.
