Allen-Bradley 1606-XLDNET8 Power Supply Module
Product Dimensions：
The Allen-Bradley 1606-XLDNET8 is a specialized power supply from the Essential and Performance line, specifically designed to meet the requirements of DeviceNet networks. It provides the necessary 24V DC power to the network media to drive communication and power field devices.
Product Detailed Description
The 1606-XLDNET8 is a NEC Class 2 rated power supply. This is a critical distinction, as it limits the output power to 100VA to ensure safety in specific wiring environments. It is a high-efficiency, DIN-rail mounted unit that converts AC input (100–240V) into a stabilized 24V DC output tailored for the sensitive electronics of a DeviceNet communication bus.
Technical Parameters
| Parameter | Specification |
| Input Voltage | 100 to 240 V AC (Wide Range) |
| Output Voltage | 24 V DC (\pm 1\%) |
| Output Current | 3.8 A (to comply with Class 2 limits) |
| Output Power | 91.2 W (Max 100 W) |
| Efficiency | > 90% |
| Certifications | UL Listed (Class 2), CE, RoHS |
| Dimensions | Approx. 32 x 124 x 102 mm (W x H x D) |
| Connection Type | Screw terminals (pluggable for some versions) |
Product Advantages
- NEC Class 2 Compliant: Allows for simplified wiring and installation because the output power is limited, reducing the risk of fire and electrical shock.
- Low Ripple & Noise: Specifically filtered to ensure that the 24V DC power does not introduce electrical interference into the DeviceNet data lines.
- Compact Footprint: The slim design saves valuable space on the DIN rail inside control cabinets.
- High Reliability: Features long service life and high Mean Time Between Failures (MTBF), essential for industrial networks where a power failure stops all communication.
- Overload Protection: Includes intelligent current limiting to protect the DeviceNet cable from damage due to excessive load.
Important Considerations & Precautions
- Network Segmenting: Because this is a Class 2 supply (limited to ~4A), larger DeviceNet networks may require multiple 1606-XLDNET8 units to power different segments of the network.
- Voltage Drop: Ensure that the power supply is placed centrally or near high-draw devices to minimize voltage drop over long DeviceNet “trunk” lines.
- Airflow: Provide at least 40mm of clearance above and below the unit, and 5mm on the sides, to ensure proper convection cooling.
- Class 2 Wiring: To maintain the Class 2 rating, ensure that the field wiring used meets the specific gauge and insulation requirements mandated by local electrical codes.
Product Applications
The 1606-XLDNET8 is used exclusively in industrial automation environments:
- DeviceNet Networks: Providing “Bus Power” to the V+ and V- wires in a DeviceNet cable for sensors, actuators, and motor starters.
- Automotive Assembly: Powering I/O blocks on conveyor systems where DeviceNet is the primary control network.
- Material Handling: Used in sorting facilities to power distributed network modules across large areas.
- General Machine Control: Integrating small-scale DeviceNet nodes into a larger Allen-Bradley ControlLogix or CompactLogix system.
