- Verify the complete 1771-NOC/B nameplate before treating the unit as a Series B replacement
- Rockwell Automation documents the base 1771-NOC as an eight-output high-resolution isolated analog module
- Preserve the PLC-5 block-transfer configuration and remote termination arrangement while revision evidence is pending
Allen-Bradley 1771-NOC/B is a Series B-marked 1771-NOC module whose exact revision-specific differences require direct manufacturer evidence.
Rockwell Automation's base 1771-NOC manual documents an eight-output high-resolution isolated analog output module for 1771 I/O and PLC-5 applications using block-transfer programming and remote termination.
The located direct official manual does not state the /B revision differences. Confirm the full installed label or an exact Rockwell revision record before treating 1771-NOC/B as a direct replacement.
Availability, condition, price, and shipping time for 1771-NOC/B are confirmed during quotation.
