Overview
The DBK24 is a 3×8-channel digital output chassis that connects to the LogBook’s, DaqBook’s, or
DaqBoard’s [ISA type] P2 Digital I/O Port or, for a DaqBoard/2000 Series board [except DaqBoard/2003]
to an appropriate P4 adapter. These adapters are discussed in the DBK200 Series document modules.
The DBK24 provides 500 V isolation from the system and from channel-to-channel. Up to 8 DBK24s can
attach to the LogBook, DaqBook, or DaqBoard (not the Daq PC-Card), offering up to 192 bits of isolated
digital output.
The DBK24 provides screw-terminal access to each of its 24 isolated outputs. A slide-out PCB allows
easy access to the controls and connectors. The output circuitry allows output voltages as high as 60 V at
currents up to 1 A.
The local digital I/O cannot be used while any DBK24s are attached.
