MedeaWiz® Sprite® 4K
.
PLC Wiring to the I/O Port
The Sprite® 4K can be triggered from a Programmable Logic Controller using relay "dry
contacts" or a transistor output.
The sinking output above is the preferred method if dry contacts are not available.
The Sprite® 4K has an internal 22K 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® 4K. 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® 4K.
