ABB AC500 PLC - Functionality; Electrical Connection

The inputs/outputs are group-wise electrically isolated from each other.
All other circuitry of the module is electrically isolated from the inputs/outputs.
Functionality
Parameter Value
Digital inputs Max. 16 (24 VDC), can be used as sink inputs
Digital outputs Max. 16 (transistor outputs 24 VDC, max. 0.1 A)
LED displays For signal states
Internal power supply Via I/O bus
External power supply Via the terminals ZP and UP (process voltage 24
VDC)
Electrical Connection
For a detailed description of the mounting, disassembly and electrical connec-
tion of the module, please refer to the System Assembly chapter Ä Chapter 2.5
“AC500-eCo” on page 1192.
The electrical connection is established out by using the 20-pin Interfast connector. For further
information, refer to the Interfast documentation.
