Output
Multifunction programmable
relay contact output. Contact
ratings: 250Vac - 2A (cos
φ=1),
30Vdc - 1A, 250Vac - 1A
(cos
φ=0.4). Standard default
setting: Monitoring of status of
inverter’s protection function.
Activation of the protection
function causes circuit FLA-
FLC to close and circuit FLB-
FLC to open.

■ Sink logic (negative common)/source logic (positive common)
⋅⋅⋅ Logic switching of input output terminals
Current flowing out turns control input terminals on. These are called sink logic terminals. (For all
models except models with a built-in noise filter, control input terminals are factory-set to sink
logic.) The general used method in Europe is source logic in which current flowing into the input
terminal turns it on.
