Remote I/O devices
Connection of sensors to control systems
Remote I/O devices enable the decentralised acquisition and control of process data by connecting sensors and actuators to the control system via a bus interface. They significantly reduce the amount of wiring required and therefore save time, money and labour.
Digital modules - reading and outputting digital signals
Digital I/O modules (input/output modules) are used for digital input and output from the sensor to the controller (e.g. a programmable logic controller). They are used to record process signals from sensors and output control commands to actuators.
IO-Link master - interface between controller and IO-Link devices
An IO-Link master is a central element in an IO-Link system. It serves as an interface between the higher-level controller (e.g. a programmable logic controller) and the connected IO-Link devices, such as sensors or actuators.
IO-Link hub - for collecting and forwarding digital signals
An IO-Link hub is a device used in industrial automation systems to facilitate communication between digital (non-IO-Link) sensors, actuators and an IO-Link master. The hub acts as a node that collects the signals from several classic or digital sensors and actuators and forwards them to the master via a single IO-Link port.
