The Auxiliary I/O Board’s inputs are generic and do not require any configuration. Analog Inputs and Binary Inputs are defined by their associated numbers. Binary Input #1 through Binary Input #4 and Analog Input #1 through Analog Input #4 will reside on the Auxiliary I/O Board (A4) with its dipswitch configured for Auxiliary I/O Board #1.
Each relay has a dedicated configuration for:
- alarm condition or status point mapping
- latching or non-latching
- time delay
Auxiliary I/O Board Relays can be mapped to indicate the state of any ATevo alarm or status point. Each relay can be independently configured to latch when the alarm or status point associated with the relay becomes active. Once latched, the relay must be cleared manually by initiating the RESET LATCHED RELAY feature (see Section 9.6). All relays have a time delay configuration. The relay will not change to active state until the associated alarm or status point has changed to active state and remains in active state for the configured time delay.
To make changes to parameters for a relay on the Auxiliary I/O Board:
MENU > RELAYS > ‘Relay Configuration’ > select relay from options >
select parameter as in the toggles below:
- Relay Alarm Configuration
-
To change the alarm condition assigned to the relay:
MENU > RELAYS > ‘Relay Configuration’ > select relay from options
(as shown above) > ‘Fault:’ > select condition from list![]()
- Relay Latch Configuration
-
To change the latching control configuration for a relay on the
Auxiliary I/O Board:
MENU > RELAYS > ‘Relay Configuration’ > select relay from options
(as shown above) > ‘Latching:’ > select from 2 latching options![]()
- Relay Time Delay Configuration
-
To change the delay time configuration for a relay on the Auxiliary I/O Board:
MENU > RELAYS > ‘Relay Configuration’ > select relay from options (as shown above) > ‘Delay:’ > set digits as desired![]()
- Factory Default Alarm Relay Configuration

Unless otherwise specified, the ATevo Auxiliary I/O Board (A4) will ship from the factory with the following Alarm Relay Configuration:
Factory Default Alarm Relay Configuration Relay Name Latching Delay . #1 High DC Voltage disabled 30 seconds . #2 Low DC Voltage disabled 30 seconds . #3 DC Output Failure disabled 30 seconds . #4 Low AC Supply disabled 30 seconds . #5 Positive Ground Fault disabled 30 seconds . #6 Negative Ground Fault disabled 30 seconds
