2.5.4.1 Power supply
The processor modules PM50x2 can be connected to the 24 V DC supply voltage via a remov-
able 3-pin spring terminal block or a 3-pin screw terminal block.
Table 187: Removable terminal block for the supply voltage 24 V DC
3-pin spring terminal block 3-pin screw terminal block
The terminal block is available as a set for AC500-eCo V3 processor modules.
Basic CPU (PM5012) Standard CPUs (PM5032, PM5052) and
Pro CPUs (PM5072)
Spring type Screw type Spring type Screw type
TA5211-TSPF-B TA5211-TSCL-B TA5212-TSPF TA5212-TSCL
Further information on the terminal blocks concerning power supply and onboard inputs/outputs
are provided under pluggable connectors for screw and spring connection
