PCD3.C200 for 4 modules with power supply
The PCD3.C200 supplies the following module carriers PCD3.C100 and PCD3.
C110 with current up to a certain load limit. The load is calculated by the power
consumption of the I/O modules used. If this load is exceeded, a PCD3.C200 I/O
Bus Repeater will continue to help to secure the internal +5 V and V + for another
I/O bus segment.
Comment: The term I/O bus segment refers to all module carriers from the
current CPU or PCD3.C200 to another PCD3.C200 repeater.
● For 4 pluggable PCD3 I/O modules
(freely selectable)
● Can be connected to PCD2.Mxxx,
PCD3.Mxxx0, PCD3.RIO and
PCD3.LIO
● Expandable with PCD3.LIO
(PCD3.C100, .C110, .C200)
● Serves as a bus repeater and internally
provides + 5 V and V + for a segment of
I/O modules
