B&R Digital Output Module (DO135 / 7DO135…)
The B&R DO135 refers to a digital output module from B&R's modular I/O range — most likely the module whose full order number is 7DO135.70 (which you sent earlier). The 7DO prefix marks B&R's digital output family, used to switch binary on/off signals to field devices such as relays, contactors, solenoid valves and indicator lamps. Installed in the modular I/O rack, it delivers the control system's discrete output commands to the machine.

Source note: The 7DO prefix identifies this as a B&R digital output module. The exact number of output channels, output type (relay / transistor), switching voltage and current rating, isolation and electrical characteristics must be confirmed against the official B&R datasheet for 7DO135.70 before ordering.
Typical Application Scenarios
- Actuator Control: switching relays, contactors and solenoid valves.
- Indication & Signalling: driving indicator lamps and signal devices.
- Machine Control: issuing discrete control commands from machine logic.
- System Retrofits: replacing digital output modules in existing B&R installations.
- Spare Part Replacement: servicing modular I/O in the field.
Frequently Asked Questions
