ABB AC500 PLC - Technical Data of the Configurable Digital Inputs;Outputs; Technical Data of the Digital Inputs;Outputs if used as Inputs

Parameter Value
Cooling The natural convection cooling must not be
hindered by cable ducts or other parts in the
switch-gear cabinet.
Altitude > 2000 m: On request
NOTICE!
Attention:
All I/O channels (digital and analog) are protected against reverse polarity,
reverse supply, short circuit and continuous overvoltage up to 30 VDC.
Multiple overloads
No effects of multiple overloads on isolated multi-channel modules occur, as
every channel is protected individually by an internal smart high-side switch.
Technical Data of the Configurable Digital Inputs/Outputs
Each of the configurable I/O channels is defined as input or output by the user program. This is
done by interrogating or allocating the corresponding channel.
Parameter Value
Number of channels per module 8 inputs/outputs (with transistors)
Distribution of the channels into groups 1 group of 8 channels
If the channels are used as inputs
Channels C0...C7 Terminals 1.0...1.7
If the channels are used as outputs
Channels C0...C7 Terminals 1.0...1.7
Reference potential for all inputs/outputs Terminal 1.9 (ZP = Minus pole of the process
supply voltage)
Indication of the input/output signals 1 yellow LED per channel, the LED is ON
when the input/output signal is high (signal 1)
Monitoring point of input/output indicator LED is part of the input circuitry
Galvanic isolation From the rest of the module
Technical Data of the Digital Inputs/Outputs if used as Inputs
Parameter Value
Number of channels per module Max. 8 digital inputs
Reference potential for all inputs Terminal 1.9 (negative pole of the process
supply voltage, signal name ZP)
Input current per channel
Input voltage +24 V Typ. 5 mA
