In Germany and some other European countries, the grid company uses the
Ripple Control Receiver to convert the grid dispatching signal and send it in a
dry contact manner. In this case, the plant needs to receive the grid dispatching
signal in the dry contact communication manner.
Reactive power dry contact
Wiring of the reactive power dry contact is shown in the figure below:

AI/DI function
On the bottom of the Logger1000, there are 4 groups of ports (1+, 1-, 1+, 1-, 2+,
2-, 3+, 3-, 4+, 4-) compatible with the AI/DI function.
When enabling the AI/DI function, use a power cable to connect the "24V
OUT+" port and the DI port, shown by the green line in the "fig. 8-2 Wiring of the
reactive power dry contact".
Active power dry contact
