PKONE Extension - Powering the Core of the PKONE System

​

Extension devices are the backbone of the PKONE system. They monitor switch and opto states while controlling coils, servos, and magnets with precision. Each Extension offers a high number of input and output connections, meaning most pinball machines can be fully driven using just two Extension devices.

The PKONE system supports up to eight connected devices, providing more than enough connectivity for even the most complex pinball builds.

Like the rest of the PKONE ecosystem, Extensions use standard RJ45 Ethernet ports and off-the-shelf Ethernet cabling. This simplifies setup, delivers common voltages without additional wiring, and ensures a clean, modular installation across the entire system.
