FAQs

Q1: Can I use the 1753-OB16 for standard (non‑safety) outputs?
Yes, it can control standard 24V DC loads. However, when used in safety circuits, outputs must be configured and validated through RSLogix Safety software to maintain safety integrity.

Q2: What safety performance level does this module support?
It is certified for SIL 3 per IEC 61508 and PLe Category 4 per ISO 13849‑1.

Q3: Does the module support hot‑swapping (RIUP)?
Yes, the 1753‑OB16 supports Removal and Insertion Under Power when properly configured, allowing replacement without full system shutdown.

Q4: How many outputs can I use at full 2A current?
Each output supports 2A max, but each group of 8 outputs has an 8A total limit. At 60°C, derate to 1A per output.
