A three-way power connector is used to connect Power+, Power– (ground), and
earth. The module requires an input voltage of 10 – 28Vdc. Refer to the technical
specifications section in this document.

2.4 Analog (HART) – Single Device
The Analog HART channels are connected using a two-way connector. The input
channels (PLX51-HART-4I) are internally loop powered and therefore can be
connected directly to the field device signal terminals.
