| Parameter | Value |
|---|---|
| Standard output | 2.7 A / 60 VAC/DC in source; AC peak-versus-RMS definition must be confirmed |
| Custom maxima mentioned | 3.6 A or up to 400 V; not a combined rating |
| Input polarity | NPN / PNP / dual versions; confirm exact model |
| Barrier / cage terminal | M3 at 7.62 mm / M2.5 at 5 mm |
| Mounting | 35 mm DIN or screws |
| Wire / torque / environment / mass | Exact model-specific specification required |
Selection & installation notes
- The naming example calls an N-coded model dual-input and independent-output, but the table lists NPN and eight-per-COM. Use the ordered model wiring diagram to resolve this conflict.
- Confirm whether the 60 V AC figure is peak or RMS and obtain the exact semiconductor datasheet. Do not use optional 3.6 A and 400 V maxima together.
- Grouped outputs share COM limits; request total-current and thermal derating. A 2.7 A per-channel class is not a simultaneous full-load guarantee.
- The source intro gives 65.5 mm for six channels while its table gives 65 mm. Confirm the production drawing. Isolate supplies before using the relay extraction tool.
