Sourcing/sinking describes the current flow between the I/O module and the field device. Sourcing PLC inputs supply current to sinking field devices. Sinking PLC inputs are driven by a current sourcing field device. Field devices connected to the negative side (DC Common) of the field power supply are sinking field devices. Field devices connected to the positive side ( V) of the field supply are sourcing field devices. #IndustrialAutomation #FieldDevices | RealPars

Sinking and Sourcing PLC Outputs Explained ▶ Check out the full blog post over at https://realpars.com/sinking-output/ In this video, we’re going to talk about Sinking and Sourcing PLC digital output modules and how they connect to field devices. Digital output modules can be solid state or dry relay. The purpose of a PLC Digital Output module is to operate or control a DC voltage physical device based on field device conditions connected to an input module and decisions made by the PLC program.
