B&R X20DO8332 8-Channel 2A High-Current Output Module

The B&R X20DO8332 is intended for actuators that require more current than a conventional 0.5 A output can provide. Its eight source outputs are rated at 2 A each, arranged in two groups with a nominal current limit of 4 A per group and 8 A per module.

The actuator supply is connected directly to the module, so an additional X20 potential-supply module is not required for these outputs. This direct-supply architecture and higher current capacity clearly distinguish X20DO8332 from X20DO9322 and X20DO6322.

Key Features

• Eight high-current digital outputs
• 2 A nominal current per channel
• 8 A total module current
• Direct external actuator supply
• Integrated output protection
• Supply-voltage and output diagnostics

Typical Applications

• Larger solenoid valves
• Industrial contactors
• DC brakes and clutches
• High-current relay coils
• Machine actuators with elevated starting current

FAQ

Q: Does each output continuously provide 2 A?

A: Each channel is rated at 2 A, but the 4 A group limit, 8 A module limit and temperature derating must also be observed.

Q: Is a separate supply module required?

A: The output supply is fed directly into X20DO8332. A separate potential-supply module is not required for the actuator supply, but the specified external fuse is necessary.

Q: Can X20DO8332 replace X20DO9322?

A: Not directly in every installation. The modules have different channel counts, supply arrangements and current ratings, so wiring and project configuration must be checked.
