Ordinary IO
In this mode, the module works as a standard IO module, inputs and outputs are not
related with each other.
Monostable Relay
In this mode, both rising and falling edge on the special input change the output state.
The action of monostable relay can be executed remotely by changing the state of bit
from false to true in the Command register (40020). Outputs can be also overwritten by
the Digital Oouput register (40018), which allows remote control from BMS.
Bistable Relay
In this mode, only the rising edge on the special input changes the output state. The
action of bistable relay can be executed remotely by changing the state of bit from false
to true in the Command register (40020). Outputs can be also overwritten by the Digital
Output register (40018), which allows remote control from BMS.
Time Relay NO [ms]
In this mode, if the output value is false, the rising edge on the special input sets the
output to true. Every falling edge on the special input starts the counter from the
beginning, which means that the output will stay true for a time defined in the Time Value
register (expressed in milliseconds), counting from the last falling edge of the special
input. The time relay action can be executed remotely by changing the state from false to
true in the relevant Command register (40020). Outputs can be also overwritten by the
Digital Output register (40018), which allows remote control from BMS.
Time Relay NC [ms]
In this mode, if the output value is false, the falling edge on the special input sets the
output to true. Every rising edge on the special input starts the counter from the
beginning, which means that the output will stay true for a time defined in the Time Value
register (expressed in milliseconds), counting from the last rising edge of the special
input. The time relay action can be executed remotely by changing the state from false to
true in the relevant Command register (40020). Outputs can be also overwritten by the
Digital Output register (40018), which allows remote control from BMS.
Time Relay NO [s]
In this mode, if the output value is false, the rising edge on the special input sets the
output to true. Every falling edge on the special input starts the counter from the
beginning, which means that the output will stay true for a time defined in the Time Value
register (expressed in seconds), counting from the last falling edge of the special input.
The time relay action of can be executed remotely by changing the state from false to
true in the relevant Command register (40020). Outputs can be also overwritten by the
Digital Output register (40018), which allows remote control from BMS.
