PLC Output Interfacing
The Sprite® can be controlled from a Programmable Logic Controller using “dry contacts” like a
push button, or voltage output.
The sinking output is the preferred method if dry contacts are not available.
The Sprite® has an internal 10K pullup so the Sourcing output requires a low resistance from
Output to Common to pull the Sprite’s internal voltage down to a “LOW”. The 1K* shown is an
example and can vary depending on the +V voltage. Consider the Watt rating of the resistor.
Do not allow a negative voltage to be applied to the Sprite®. Do not share PLC outputs with
relays, motors or solenoids /valves. These devices can produce negative voltage spikes. Keep
them on separate isolated outputs away from the Sprite®.
