📏 Physical Specifications
| Feature | Specification |
|---|---|
| Mounting | Vertical DIN rail mount (non-isolated, mechanically supported); rack mount not applicable for vertical configuration |
| Dimensions | - 2-Position Baseplate: Specific dimensions not listed, but similar to other 2-position vertical baseplates (refer to Figure 10 for vertical layout) - Likely ~124 mm height, ~150–200 mm width, ~50–75 mm depth (estimated from Figure 10) - Clearance for FCP270 modules required (per PSS 21H-1B9) |
| Mass | Estimated ~0.3–0.5 kg (based on 0.91 kg for 8-position baseplate; 2-position is smaller) |
| Material | PC and ABS, inflammability UL94 V0 |
| Color | Black |
| DIN Rail Fasteners | 2–4 fasteners (depends on baseplate size, typical for 2-position) |
| Cabling | - Power Cabling: 0.4 m (16 in) to 2.1 m (7 ft) - Module Fieldbus Cabling: 0.125 m (5 in) to 60 m (198 ft), total allowable length 60 m (198 ft) |
| Connectors | - Labeled connectors for A/B Module Fieldbus, power, and optional time strobe - Module guides ensure correct FCP270 insertion |
