Digital electronic outputs (switching transistors)
The digital electronic outputs (switching transistors, P channel, 24V switching) of the
CAN-I/O-modules switch 24 VDC process voltage. Integrate the outputs as follows:
The reference potential (+24VDC, GND) for the external actuator (in the principle
drawing a simple resistor) is the process voltage.
The digital electronic outputs
Out2.1 to Out2.8 at CAN-I/O-Module
CAN-IO 16/16
= port2 (X7)
Out1.1 to Out1.8 at CAN-I/O-Module
CAN-IO 8/12-4/1
= port1 (X6)
can be loaded with max. 350mA on each output.
IMPORTANT when using the CAN-I/O-Module
CAN-IO 16/16,
here
obtains for digital electronic outputs Out2.1 bis Out2.8 = Port2 (X7):
If the integrated D/A converter is used for analog output then port2 is reserved. That
means port2 is not longer available for digital outputs. To prevent confusions you can
deactivate port2 by removing Jumper1 (refer the next chapter
Analog output
).
Through this the port2 LEDs are also deactivated.
Driving inductive loads on digital outputs (for example relays) put parallel to
every load (relay) a catch diode (anode to GND).
