Compatibility of Pre-Actuators with Outputs
-
Compatibility of DC pre-actuators and outputs:
-
comply with the output’s maximum current and maximum switching frequency as specified in the table of characteristics,
-
where low consumption pre-actuators are used, special attention must be paid to the leakage current of the idle output, to ensure that the following inequation is satisfied:
I nominal ≥ (50 x I leakage)
given that:
I nominal = current consumed by the pre-actuator,
I leakage = leakage current in idle output state.
-
Compatibility of tungsten filament lamps and transistor outputs (static current):
-
for outputs with protection against short circuits, the maximum power of the tungsten filament lamps specified in the table of characteristics must be complied with. If not, the lamp’s pick-up current might cause a tripped output at the time of power-up.
-
Compatibility of AC pre-actuators and relay outputs:
-
Compatibility of lamps and bidirectional triode thyristor outputs:
-
Compatibility of AC pre-actuators with relay bidirectional triode thyristor outputs:
-
comply with the specified maximum current,
-
where low consumption pre-actuators are used, special attention must be paid to the leakage current of the idle output, to ensure that the following inequation is satisfied:
I nominal ≥ (50 x I leakage)
given that:
I nominal = current consumed by the pre-actuator,
I leakage = leakage current in idle output state.
