microBlox uB DC Power Module

The uBDC1 power module allows a back panel populated with I/O modules to operate off DC power voltage levels other than 5V. This optional module plugs into a special socket on the back panel to convert a power supply voltage from 10-32V DC to 5V/1A which will drive up to 16 I/O modules. uBDC1 modules include over-voltage, reverse-voltage and short-circuit protection (current limiting).

With the uBDC1 power module, users can also implement redundant power methods for the back panel. In redundant applications, the uBDC1 becomes the primary power source.
