DO232 Digital Output Module Bachmann

Product Description
The DO232 (Order Number: 00012240-00) is a high-density actuator interface module for the Bachmann M1 automation system. With 32 independent digital outputs, it provides a robust and space-efficient solution for driving industrial loads such as relays, contactors, solenoid valves, and signaling devices. Its single-slot form factor allows extensive system expansion without increasing the control cabinet footprint.

The module features integrated protection circuitry:

• Each output is safeguarded against short circuits and thermal overloads

• Automatic restart occurs once a fault is cleared

• 500 V RMS galvanic isolation between the system bus and field electronics protects the central processor from local faults or electrical noise

This makes the DO232 ideal for mission-critical applications in sectors such as energy, maritime, and heavy industry.

Technical Specifications

Application Scenarios

• Wind turbines: Control of braking systems, lighting, and cooling fans

• Manufacturing assembly lines: Rapid, deterministic triggering of multiple pneumatic valves

Technical FAQ

Q: Can I parallel the outputs to drive a higher current load?
A: Yes, multiple outputs can be connected in parallel to increase the total current. Ensure they are switched simultaneously in the PLC program for even load distribution.

Q: What happens if a single channel experiences a short circuit?
A: The affected channel shuts down automatically to protect the module, while the remaining 31 channels continue normal operation. Once the short is cleared and the output is toggled, the channel resumes standard function.
