Digital outputs (relay outputs)
The digital relay outputs of the CAN-I/O-modules switch 24V-DC 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 relay outputs
Out1.1 to Out1.8 at CAN-I/O-Module
CAN-IO 16/16
= port1 (X6)
Out2.1 to Out2.4 at CAN-I/O-Module
CAN-IO 8/12-4/1
= port2 (X7)
can be rated with 5A for each output.
Driving inductive loads on digital outputs (for example relays) put parallel to
every load (relay) a catch diode (anode to GND).
