Connecting equipment to Variable DC Modules
The Variable DC Module (model
VDC-4
) has four 0 to 10 V outputs for controlling variable
frequency drives or FanDRIVEs.
The ratings of the equipment you connect must not
exceed the ratings of the Variable DC Module.
0 to 10 VDC, 2K Ω load
FanDRIVEs
FanDRIVEs are for controlling AC variable fans, and are a cost-effective way to increase the
capacity of your fan control system. Installation is simple and there is no additional configuration
required; FanDRIVEs follow the programming of the AutoFlex.
There are two FanDRIVE models available. Model FD-2-7 has two 7 FLA stages, model FD-1-14
has one 14 FLA stage. For more information about FanDRIVEs, visit

To connect variable frequency drives or FanDRIVEs
The disconnect relay for the variable frequency drive is a relay on an RM-4 module.
Configure the relay to follow the variable DC output. For more information, refer to
the online help at the AutoFlex Connect display.
