Relay Card 1977xx

An initialization is mandatory after switching on the relay cards. The discovered relay card addresses are automatically entered in the relay card 1977xx menu and can be selected by choosing them from the addr. pull-down menu. A name can be assigned to each card and to each of its eight single relays. A check mark activates the current supply.

OK transfers the settings and switching states to the relay cards. The relay switching of several cards does not happen simultaneously but with a delay of several milliseconds in between the cards.

For further information please refer to the relay card manual.
