Notes

Notes on operationObserve the maximum switching capacity of the relays used
Notes on operationDo not connect adjacent channels to SELV/ PELV and voltages dangerous to the touch.
Notes on operationThe necessary requirements for insulation (basic insulation or reinforced insulation) from adjacent modules (in DIN-rail direction) must be realized by applying suitable measures (e. g., partition plates).
Notes on operationAdjacent channels are not suitable for switching different line conductors.
