Module Wiring-Inputs; Input Wiring, 3-Wire Sensors - Electro Cam PLUS PS-5000 Series Programming & Installation Manual

Sinking or Sourcing (as pertaining to Electro Cam Corp. products)
Sinking means that when the logic is true and the output (or input device) is ON, the output (or input device)
is providing a DC common or ground to the connected device.
Sourcing means that when the logic is true and the output (or input device) is ON, the output (or input device)
is providing a +DC voltage to the connected device.
This information is important when interfacing an Electro Cam Corp. product with another electronic device. If you are using an Electro Cam Corp. product
input to an Allen-Bradley 1746-IN16 "sinking" input card* or similar A-B device, you have to supply a +DC voltage (Electro Cam Corp. Sourcing output)
to this card, NOT a DC common or ground. In these cases, Sinking is what the card does with the input voltage; sinks it to common or ground.
*Other manufacturers include, but not limited to: Koyo (formerly GE Series 1, Texas Instruments, or Siemens SIMATIC PLS's) that use descriptions
similar to Allen-Bradley.
AC Input
• Input devices can be mechanical contacts or solid state.
• The load 10K load resistor shown may be needed if the AC input device
has off-state leakage, such as a solid state triac.
Sourcing
• For controllers using input/output modules.
