But a separate protection for the supply of the outputs is a legitimate way. In any case, the supply connections of the outputs to the supply and a GND line are connected. www.pixtend.com 16 / 119 Copyright by Qube Solutions GmbH... - Page 17 However, the supply current of the modules must under no circumstances be routed via this connection. Transmission errors, incomprehensible communication behavior and possibly overloading, usually thin bus lines, can be caused by this. www.pixtend.com 17 / 119 Copyright by Qube Solutions GmbH...

As a rule, voltages greater than 50 V (DC or AC) are referred to as dangerous voltages. The most common dangerous voltage is the mains voltage with 230 or 115 V AC. But there are also other dangerous tensions. www.pixtend.com 51 / 119 Copyright by Qube Solutions GmbH... - Page 52 The safety mechanisms (miniature circuit breaker, personal protective switch / residual current circuit breaker / fault current switch) are able to trip and restore the entire system to a safe state. www.pixtend.com 52 / 119 Copyright by Qube Solutions GmbH...

Page 110: Analog Outputs
All six analog outputs are supplied via the central power supply of PiXtend eIO and do not require a separate infeed. All analog outputs on PiXtend comply with the requirements of the PLC standard IEC / EN 61131-2. www.pixtend.com 110 / 119 Copyright by Qube Solutions GmbH... - Page 111 The external supply of voltages (for example 24 V) to analogue outputs is not permitted and can lead to the failure of the outputs. Always make sure that there is no wiring fault before connecting the analog outputs. www.pixtend.com 111 / 119 Copyright by Qube Solutions GmbH...
