Product Description

The B&R 2DO428.6 Digital Output Module is a high-performance device for the B&R System 2010 which has been optimized for rapid and reliable digital signal processing in industrial automation. It was launched onto the market in 2010 and comes with thirty-two transistor outputs that are divided into four groups of eight outputs each, thus providing electrical isolation among various groups to enhance safety and reduce disturbance to suit different applications within the industry. The nominal switching voltage supported by each output is 24 VDC, with the minimum being 18 VDC while the maximum can reach up to thirty volts DC. This module may carry continuous current per output not exceeding 0.5 A, per group four amperes whereas sixteen amps for the whole unit is its maximum. Overload protection resets itself after about five seconds, thereby ensuring reliability during operation and long service life.

The PCC on this module are isolated from each other as well as from the outputs, but there is no isolation between individual channels within a group. The time required by such a device to switch over from logic zero state into logical One state equals approximately five microseconds (and may be at most one hundred ten microseconds), while from logic one into zero it is around sixty microseconds (up to one hundred microseconds). The given block supports resistive loads whose maximal switching frequency does not exceed five hundred hertz.

There exist additional functions like internal safeguarding against peak overvoltage till fifty-five volts (VDE160) plus reverse voltage guard off for inductive loads rated between forty-five and fifty-five volts DC. Also, the short-circuit current range lies within naught point seven five through one point five amperes together with leakage current when turned off equaling zero point three milliamperes, while maximum consumed power amounts up to five watts internally and two more watts externally per group towards terminals side under a twenty-four volt supply.
