Selection & installation notes
- The 12 A DC relay code appears alongside a 5 A fuse and 10 A screw / 8 A spring terminals. Do not interpret it as a 12 A complete-module rating; confirm the actual assembly capacity.
- The source also lists a 16-channel 8×2 assembly at 260 mm length, separate from the 252 mm unit. Confirm variant and drawing; mass is not specified.
- Semiconductor fuses require the correct time-current characteristic and AC/DC breaking capacity. A 250 V marking alone does not establish suitability for a DC fault.
- Multiple active channels share the thermal environment. Confirm cooling, derating, load surge, shared-input limits and protection coordination; OFF-state SSR output is not isolation.
