6.6.2 AC CONTROL
The ECB’s AC CONTROL section (A0-A7) are digital outputs at a 5-volt logic level. They are primarily used as the
control signals for high power AC relays. LEDs adjacent to each output indicate the status. When an LED is on, it
indicates the digital output is active and it’s (-) pin is being pulled to a logic low. The (+) pin of each digital output is
hard wired to +5 VDC.
6.6.3 A/D INPUTS
The ECB’s A/D INPUTS section (AD0-AD7) has an 8 channel, 14-bit, 5-volt analog to digital converter system. Each
connector also has 12 VDC power available to directly power the connected devices or sensors.
