Program Logic Control(PLC) adalah suatu alat kontrol yang terdiri dari beberapa komponin, disini saya akan memberikan contoh beberapa komponen PLC siemens ,seperti Power Supplies,CPU, Modul Digital dan Modul Analog.

1.Power Supplie

Specification:

• Load power supplies for S7-300/ET 200M

• For conversion of the line voltage to the required oper-ating voltageof 24 V DC

•Output current of 2 A, 5 A or 10 A

2.CPU

Specification:

• The compact CPU with integrated digital inputs and out-puts

• For small applications with high requirements in terms of   processingpower

•With process-related functions

3.MODUL DIGITAL

                          Spesification:

•Digital I/O for the SIMATIC®

S7-300®

• For connecting switches

and 2-wire proximity

switches (BERO)

4.MODUL ANALOG

                          Spesification:

• Analog inputs for the SIMATIC® S7-300®

• For the connection of voltage and current sensors, thermocouples, resistors

and resistance thermometers
