- Current Consumption: Typically 25 mA at 24 Vdc
- Dimensions (H x W x D): 90 mm x 90 mm x 110 mm
- Module Weight: 35 g (1 oz)
- Maximum Transmission Distance: Up to 1,200 meters (3,937 feet) per channel when deployed with shielded twisted-pair cabling having a minimum cross-sectional area of 0.5 mm² (24 AWG)
- Operating Temperature Range: 0°C to 49°C
- Relative Humidity Range: 10% to 93% non-condensing
