SMART T-Connector with DCD
SEU-1/0-T45 Series
2.5.3 Wiring Additional Power Supplies
For guidance on maximum total cable length and maximum number of devices before an additional power supply may
be needed, see Figure 7 on p. 10. For using DCD information to monitor the individual device voltages, see Daisy Chain
diagnostic (DCD) Information on p. 11.
In a long series or series with many DCD devices, the voltage at all devices must stay above 19.5 V for proper operation.
An additional power supply may be required to maintain a minimum of 19.5 V at all devices. There are two options to
connect an additional power supply.

Note:
Option 1 can only be used in combination with ATS-M12/4-M12/8 connector (the ATD-M12/8-M12/4 can-
not be connected to an SEU-1/0-T45-...).
Figure 5. Option 1: Use a ATD-M12/8-M12/4 Connector in series with DCD Device. If available, set the power supplies for parallel output.
Figure 6. Option 2: Replace the terminator with a power supply. The OSSD1 and OSSD2 wires at power supply #2 must be connected to +24 V DC. If
available, set the power supplies for parallel output.
