Compact CLICK PLUS CPU with Built-In Wireless Connectivity
The CLICK PLUS C2-03CPU is a stackable micro-modular programmable logic controller CPU that brings modern connectivity to small-machine automation. Alongside a 10/100 Mbps Ethernet port, an RS-232 port, an RS-485 port and a micro-B USB programming port, this CPU integrates a 2.4 GHz WiFi LAN with Bluetooth Low Energy, so the controller can be commissioned, monitored and even logged into MQTT brokers without extra gateways. A microSD card slot provides removable storage for data logging and program archiving, while a real-time clock with battery backup keeps timestamps accurate through power interruptions.
The CPU itself carries no on-board I/O. Instead, it stacks with up to eight CLICK PLUS expansion modules, letting you scale discrete and analog I/O precisely to the application. Programming uses ladder logic in the CLICK programming software (v3.0 or later), and the free CLICK Remote PLC mobile app for Android and iOS gives you on-the-go visibility over WiFi or Bluetooth.
