Product Description:
The 2DO428.6 is a transistor output module produced by B&R Automation for the System 2010 Controllers series. Installed alongside the CPU, it furnishes discrete DC switching capability that lets automated equipment energize relays, solenoids, or indicator lamps without external driver boards. Its role is to expand the base controller with transistor channels suited for moderate-current DC loads that are common in packaging, material-handling, and assembly lines.
With physical dimensions of 285 x 40 x 185 mm, the 2DO428.6 fits a standard System 2010 slice. Its internal logic absorbs only 5 W, so the heat load on the controller cabinet remains modest. The module can deliver up to 16 A across all channels while any single output is limited to 0.5 A. Four output groups hold eight channels each, and group-to-group isolation as well as output-to-PCC isolation help prevent crosstalk between external circuits. Switching duties are handled by transistors that operate up to 500 Hz, enabling pulse-width-controlled drives or fast solenoid actuation. Each group draws 2 W of terminal-side power during operation, and overload protection disconnects the channel if current thresholds are exceeded.
For field wiring, the outputs operate at a nominal 24 VDC, while the circuit tolerates peaks up to 30 VDC during transients. In the off state, a leakage current of only 0.3 mA keeps residual energy low for sensitive loads. The board exposes 32 addressable channels, providing a dense switching resource for multi-axis machinery or large indicator matrices. Internal barriers separate the transistor stage from the controller logic, ensuring that voltage spikes do not propagate toward the CPU. This separation helps protect the controller logic from disturbances created by external loads during switching.
