Output Connections, Other Devices
High current FET (transistor) outputs control DC loads and switch the voltage that is supplied to the unit. The
default power supply is 24Vdc. Lower voltage may be supplied to the board (down to 6Vdc) depending on
the requirements of the devices being driven.

1. Dimmable Ballasts & VFD Motor Controllers
Ballasts and VFD controllers that accept a 1kHz PWM signal may be controlled by the rst six (6) output chan-
nels for variable speed motor control or variable intensity lighting control. Each of the six channels operate
at 1kHz but may be set to 0, 10-90% and 100% duty independently.
Note: A low-pass lter may be constructed to convert PWM to analog voltage. Consult the light manufac-
turer to determine if PWM signals are accepted, or for advice on analog lter construction.
2. Relays & Contactors
DC powered relays, contactors and SSR's may be driven directly by the outputs. Each output is protected for
yback and surge, and is capable of up to 1A continuous current (1A max combined current.)
