This section provides information on the pin assignment of the individual interfaces and the
block diagram of the CPU 1517T-3 PN/DP.
24 V DC supply voltage (X80)
The connector for the supply voltage is plugged in when the CPU ships from the factory.
The following table shows the pin assignment for a 24 V DC power supply.
①
+24 V DC of the supply voltage
②
Ground of the supply voltage
③
Ground of the supply voltage for loop-through (maximum of 10 A permitted)
④
+24 V DC of the supply voltage for loop-through (maximum of 10 A permitted)
⑤
Spring opener (one spring opener per terminal)
Bridged internally:
