Selection & installation notes
- The relay semiconductor current is not the permissible continuous current of the complete fused module. The standard 2 A fuse constrains the 4 A relay options; the 10 A option has conflicting 2 A/5 A fuse specifications. Confirm the actual fuse, thermal derating and total simultaneous load before ordering.
- Use the approved semiconductor fuse with suitable voltage, interrupt rating and I²t coordination. Do not uprate a supplied fuse to obtain the relay headline current.
- Derate above 40 °C and allow ventilation. Surge values without pulse duration are not repetitive-load ratings.
- NPN/PNP flexibility applies to the input common only. Verify output polarity, suppression and the wiring of any custom common connections.
- Off-state leakage is not electrical isolation. Isolate power before wiring, relay replacement or MIL connection changes.
