Frequently Asked Questions (FAQs) About DI/DO Extension.
DI stands for Digital Input, and DO stands for Digital Output. DI receives ON/OFF status signals from field devices, while DO sends ON/OFF commands to control connected equipment. In monitoring and automation systems, DI and DO are commonly used for equipment status monitoring and control.
A Digital Output (DO) is a discrete signal generated by a PLC, RTU, controller, or I/O module to control external equipment. It can be used for applications such as relay operation, alarms, indicators, contactors, and breaker commands.
A Digital Input Module receives discrete ON/OFF signals from field devices and makes their status available to a PLC, RTU, SCADA, or automation controller. It is commonly used for monitoring switches, alarms, relay contacts, and breaker status.
The main difference is their function and signal direction. Digital Input receives status signals from field devices, whereas Digital Output sends control commands to field devices. Simply, DI is mainly used for monitoring and DO for control.
A Digital Input detects discrete states such as ON/OFF or 1/0, while an Analog Input measures continuously varying signals. Common analog signals include 4–20 mA and 0–10 V, which can represent parameters such as temperature, pressure, irradiance, or other measured values.
Digital Inputs and Outputs are discrete signals used for equipment monitoring and control. Digital inputs receive status information from field devices, while digital outputs send commands from the controller to connected equipment.
A Digital Input (DI) is a discrete electrical input that represents two states, typically ON/OFF or 1/0. It is commonly used to monitor switches, alarms, relay contacts, breaker status, and other equipment conditions.
A Digital Output Module generates discrete control signals based on commands received from a PLC or controller. These outputs can be used to operate relays, contactors, alarms, indicators, breakers, and other field equipment.
