# REACTOR Tension standalone vs add-on

**What is the difference between the REACTOR Tension Standalone and Add-On version?**Both versions use the same main unit and are fully interchangeable.
The difference lies in the power setup and included accessories:

**Add-On Version:**Designed for users who already have a REACTOR Motion Control Box.
It includes a power and data cable that connects directly to the REACTOR Motion control box for operation.
Ideal for integration into existing REACTOR systems.

**Standalone Version:**Includes an external power supply and an emergency hold switch.
It operates independently without requiring a Motion Control Box.
Best suited for users who need a self-contained unit or standalone setup.

**Summary:**Functionally identical main units. The difference is only in power supply and integration method.
