Power Supply 
Requirements

The customer supplied power supply should provide operating voltage and 
current to the 275 Mini-Convectron Vacuum Gauge Module as specified in 
Table 3-4. Surge current is the maximum momentary current when power is 
first applied. Operating current is the steady-state current during normal 
operation.

Current ratings for DeviceNet power are MAXIMUM. This is not an 
ISOLATED NODE.
