Terminal Terminal Function 10V-GND 24V-COM +10V Power Offers a +10V power supply, maximum output current: 20mA. Supply Offers +24V power supply, generally used as a working power supply for numeric input or output terminal, or external device power supply. Maximum output current: 200mA. +24V Power Supply Auxiliary Power Supply PLC As factory default, it is connected to 24 V power supply. When driving numeric input terminal with an external power supply, disconnect it from 24V terminal and connect it to external power supply. Common Multi-function Input Terminal Analog Input AI1-GND Analog Input Input voltage range: DC 0 - 10 V
