configuration supports relays numbered #1 through #4. The contacts of each relay are wired in a SPDT

Table 7: Relay Interface
The relays are initialized in a negated, or de-energized, state following power-up. They are
independently asserted, or energized, based on user-defined setpoints and other criteria. The assertion
of a dedicated status LED indicates when the respective relay is energized.
Note that the ROB contains no Flash memory device, therefore all configuration data is saved to the
respective channel’s AIB.
