Please note that the PLB 6001 is supplied with +24 V NC.
For the entire HSCI system, the +24 V NC power supply voltage is required to be safely separated
voltage. It must also be safely separated from the +24 V PLC!

DANGER
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 machine operating panel.
