16 Transistor–transistor logic (TTL) outputs are available on MASSO controller, these outputs can be assigned different functions in the MASSO setup screen, please see this link CLICK HERE
These outputs are designed to be interfaced to other electronics for low current signals. The maximum allowed current load on each output is 5 (mA).
For controlling things such as actuators, motors or relays please use a driver/amplifier boards such as the one show below, these can be purchased from Amazon and ebay
For more details on TTL signals, please see this article on Wikipedia
