SRMS Power Consumption

Base System 4Mb Flash / 16 Mb Ram:
120ma @ 12.2v = 1.464 Watts

Relay power consumption:
relay1 add 42ma
relay2 add 42ma
relay3 add 42ma
relay4 add 91ma
Relay Total for all relays energized: 217ma @ 12.2v = 2.647 Watts

Bare Board = 120ma + 217ma for all relays = 337ma.
337 ma @ 12.2v = 4.111 Watts
