To confirm the selection, press the key .
After selecting the output to configure, you can configure the following parameters:

The variable code that controls the relay.

The pre-alarm value.

The minimum value below which the relay is activated.

The maximum value above which the relay is activated.

The delay in connecting (ON) and disconnecting (OFF) the relay.

The status of the outputs.

The latch.
The configuration of the relay digital outputs in the expansion modules is the same as the
configuration of the relay digital outputs integrated in the device, see
“5.7.16.- RELAY DIGITAL
OUTPUTS.”.
7�2�4�- MODBUS COMMUNICATIONS
The address of the Modbus memory map depends on the position of the expansion module in
the device.
Slot 1 will be the position of the expansion module installed just behind the standard device,
and Slot 2 the next position...
As the maximum number of expansion modules that can be connected to the device is 4, there
will only be 4 slots.
7�2�4�1�- Programming of relay digital outputs
The following functions are implemented for these variables:
Function 0x04 : reading registers.
Function 0x10 : Writing multiple registers.
