ABB AC500 V3 Hardware Manual page 53

Intended pur- The device is used as an optional I/O extension module for AC500-eCo V3 CPUs (PM50x2).
pose
The inputs/outputs are group-wise galvanically isolated from each other.
All other circuitry of the module is galvanically isolated from the inputs/outputs.

Connections
The connection is carried out by using a removable 5-pin terminal block. For more information,
please refer to the chapter terminal blocks for AC500-eCo V3 system. The terminal blocks are
included in the module's scope of delivery and additional terminal blocks as spare parts can be
ordered separately.
The following block diagram shows the internal construction of the digital inputs:

The internal power supply voltage for the module's circuitry is carried out via the connection to
CPU. Thus, the current consumption from 24 V DC power supply at the terminals L+ and M of
the CPU module increases by 10 mA per TA5101-4DI.
An external power supply connection is not needed.
