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.

DBM16 Interfacing

This section will show some general examples of how to interface the DBM16 I/O lines to external devices. Caution must be taken not to exceed the DBM16 specifications, failure to do so could result in damage to the DBM16 and will void the warranty.

Before connecting the DBM16 to the SDD16 module and connecting any external device to the DBM16 determine which I/O lines on the SDD16 module are inputs and which are outputs. Once the inputs and outputs are known, set the jumpers on the DBM16 accordingly. Refer to Figure C.2.
