The 24 V terminal at the input terminal part can supply current to external equipment (not for all units).
If this terminal is used as the power supply for the input part of this unit, the remaining can be used as power supply for the
sensors.
The following current (I) can be supplied as power supply for the sensors.
(1) EH-*14*** (14-point type basic unit)
EH-*14E*** (14-point type extension unit)
I = 350 mA – (7.5 mA x number of input points that are turned on at the same time)
(2) EH-A28DR* (28-point type basic unit)
EH-A23DR*** (23-point type basic unit)
I = 280 mA – (7.5 mA x number of input points that are turned on at the same time)
