DTB25

The DTB25 connects to the SDD16 models to provide easy access to the available I/O lines. The DTB25 plugs directly into the SDD16's DB25S I/O Port connector. Each of the twenty-five pins on the connector is brought out to a terminal block. Refer to Table C.1. Dimensions: 0.5" x 2.1" x 4.3". An enclosure for the DTB25 is available.

APPENDIX C

Interface Modules for SDD16 Models

Figure C.1 - DTB25 Outline Drawing

Before connecting any external devices to the DTB25 make sure the SDD16 module has been properly configured (I/O lines defined, power-up states set). This will avoid possible damage to the module and to the external devices. Make sure not to exceed the voltage and current limits of the SDD16 module, failure to do so could result in damage to the module and will void the warranty. Refer to the Specification Section of this Manual.
