The Simple RTU: Specifications
| Mechanical | Size: 4-1/2" x 9" PC board |
| Mounting: Snap track | |
| Environmental | Operating temperature: -40 to 158 deg. F (-40 to 70 deg. C) |
| Relative humidity: 5 to 90% non-condensing | |
| Power requirements | Less than 70 mA minimum; 225 mA maximum @ 12 VDC |
