These outputs are provided as volt free relay contacts. Figure 3–7 shows the output
circuit. Maximum contact rating is 24V at 50mA per output and a minimum
current of 10mA is required.
The Alarm Relay closed contact indicates a system fault or an error, including
power loss. An Alarm is maintained until a Reset is performed to clear the error.
