DBM16
The DBM16 module provides buffering and increased power
handling for all the sixteen I/O lines of the SDD16 models. Each of
the I/O lines can be programmed as an input or as an output by
setting a jumper on the board. The DBM16
plugs directly into the SDD16's DB25S I/O Port connector.
Terminal blocks are provided for all I/O line, power, and ground
connections. Refer to Table C.2. An enclosure for the DBM16 is
available.
