Selection & installation notes
- Confirm availability of each input/output combination. The 5 A DC code appears in naming text but not the published selection row; no full part number is inferred.
- The 2K AC/DC option lacks a dedicated voltage and RMS-current table. Obtain its exact technical sheet before AC selection.
- Input thresholds and drive current are generic approximations; verify compatibility with the controller and exact input code.
- Observe DC output polarity on the body. AC A-type and DC D-type outputs are not interchangeable.
- Derate dense PCB layouts and inductive/high-inrush loads; internal RC suppression does not cover every application.
- The source suggests manual soldering ≤350 °C for 3–5 s; confirm the approved process and footprint for the exact product. OFF leakage means the output is not a service isolator.
