Outputs can be either continuous, for driving indicator lamps, or pulsed for driving Stop Action Magnets (SAMs). DC-24 can drive up to 24 indicators, or 12 SAMs. DC-48 can drive up to 48 indicators, or 24 SAMs. DC-24 is available in two versions, one for lamp mode and the other for magnet mode. -

4. Output wiring DC-24 and DC-48 are normally supplied to work with a “pull to ground” (a.k.a. “common positive”) configuration. This means that you connect one side of each lamp or magnet to positive (typically +12v) and the board energizes an output by connecting the other side to ground. -

We have no connection with either company. In theory, it is possible to “daisy-chain” any number of DC-24 and DC-48 cards together by connecting the MIDI out port of one to the MIDI in port of the next. However, for best performance, we recommend that no more than four decoder cards be connected together in this way.
