Product Questions
- Can the 1771-P4S3 be used in Series A chassis? Yes. It can be used in Series A chassis, but must be installed in designated slot pairs depending on the processor configuration. Refer to Rockwell installation instructions for slot compatibility.
- Is the 1771-P4S3 suitable for parallel operation? Yes. It can be paralleled with another 1771-P4S3 using the 1771-CT cable to increase available backplane current.
- Does the module include output protection? The module provides regulated output but does not include individual output fusing. Protection must be implemented externally if required.
- Is the module hot-swappable? No. Power supply modules must be installed and removed with system power off to avoid damage or unsafe conditions.
