A dimmer Booster card is used when the 0-10Volt load is more than the 15 ma that the iDim outputs or the 35 ma that the LTD outputs are rated to handle. The 0-10-volt output is optically isolated from the electronics of the iDim to ensure that any miss-wire on the high voltage end will not feed back into the GR2400 system.
For a system where a single GR 2408 iDim or a GR1400 LTD is being used to turn ON and off contactors and the 0-10V signal is being used to control several hundred ballasts or several LED drivers, a Distribution card is a must. It can feed up to 1/4 amp into each output which is a lot of ballasts.
Certain HID Loads require 5ma each and a signal that is inverted to 10 volts to Zero. Provision has been made for this and only requires the movement of a jumper.
The Dimmer Booster Card is powered from a separate transformer than the iDim so as to maintain isolation. It comes in the same size of enclosure as an i-DIM.
Sometimes more than 250ma is needed on just a single channel. In which case the source jumpers can be moved so that more than one channel for instance is being fed from Dimmer # 1. To assist this multiple Dimmer Booster outputs may be run in parallel to give up to 1 amp out per dimmer. For more power an additional GR 2408-iDIM should be used with more Dimmer Booster cards.
