344 HEIDENHAIN Technical Manual iTNC 530 HSCI
X7: PLC outputs Pin layout:
Current carrying capacity of the outputs: Maximum 150 mA per output. In the
event of an overload or short circuit and as a consequence of excessive
temperature, the individual PLC outputs switch off automatically. Then the
outputs will try to switch on again cyclically.

Please note that the outputs of connector X7 are powered internally by +24 V
NC, and therefore supply +24 V NC at HIGH level.
For the entire HSCI system, the +24 V NC supply voltage is required to be
safely separated voltage. The +24 V NC supply voltage must not, under any
circumstances, be connected with the +24 V PLC supply voltage, because
this removes the double basic insulation.
Each of the switching outputs at X7 supplies up to 150 mA of output
current. They are provided for driving the lamps on the operating panel.
