| Current consumption (See note.) | 350 mA max. (at startup), 120 mA average |
| Ambient temperature | Operating: -10° to 50°C Storage: -20° to 65°C |
| Ambient humidity | Operating: 25% to 85% (with no condensation) |
| Weight | Approx. 200 g |
Note: Select a power supply with excess capacity. (We recommend a minimum of 25 W.)
Wireless Interface Specifications
| Item | Specifications |
| Wave type | Spread Spectrum (direct sequence; DS-SS) |
| Communication method | Simplex (half duplex) |
| Frequency band | 2.4 GHz (2401 MHz to 2480.2 MHz) |
| Number of channels | 67 channels (based on frequency division) |
| Antenna power | 10 mW |
| Data transfer speed between wireless units | 100 kbps |
| Transmission distance (See note 1.) | Indoors: 60 m (approx. 50 m with magnetic base antennas) Outdoors: 300 m (unobstructed) |
| Relay stations | 3 repeaters max. |
| Max. number of sets in the same area (See note 1.) | 10 sets max. |
| Max. number of wireless Slaves | 64 max. |
Note:
1. The actual transmission distance depends on many factors in the installation environment.
2. The wireless system is not suitable for applications requiring real-time control.
DeviceNet Interface Specifications (Summary)
| Item | Specifications | |
| Communications functions (See note.) | Master/Slave connections | Remote I/O functions and Explicit message communications functions |
| Self-diagnostic functions | Unit | WDT error, hardware errors (such as memory and CAN errors), and setting errors |
| DeviceNet communications | Duplicate node address errors, Bus OFF detection, and connection timeout | |
| Device profiles | Communication control unit | Refer to Appendix A of the WD30 DeviceNet Wireless Units Operation Manual for various DeviceNet IDs (vendor, device type = communication adapter, product code, product revision, product name, serial number, status, and I/O unit IDs.) |
Note: FINS message communications are not supported. Explicit messages must be handled in the ladder program.
I/O Points
| Name | Number of I/O points (words used) |
| DeviceNet Wireless Master | 1,600 inputs max. (100 words) 1,600 outputs max. (100 words) |
| DeviceNet Wireless Slave | 512 inputs max. (32 words) 512 outputs max. (32 words) |
Note: Relay Stations can be used to create up to 3 levels and DeviceNet Slaves can be connected in each level.
Terminators are required when Slaves are connected to a Relay Station or Slave Station.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
