Supply voltage
24 V DC supply voltage (X80)
The connecting plug for the supply voltage is plugged in when the CPU ships from the
factory.
The following table shows the terminal 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-loaded NC contact (one spring-loaded NC contact per terminal)
Bridged internally:
① and ④
② and ③
Figure 4-1 Connection for supply voltage
If the CPU is supplied by a system power supply, it is not necessary to connect the 24 V
supply.
