Logo! 230RCE, logic module, display SV/E/A: 115V/230V/relay, 8 digital inputs/4 digital outputs, SP. 400 blocks, modularly expandable, Ethernet, integrated web server, data logging, custom web pages, standard microSD card for Logo! Soft Comfort from version 8.4, older projects executable, cloud connectivity, MQTT in all Logo! 8.4 base devices. The Logo! 8 base devices with 8 digital inputs and 4 digital outputs and a compact installation width of 72 mm integrate many well-known functions (pulse relay, stairwell timer, auxiliary relay, time relay, etc.) that can be combined in various ways. Switching programs can be easily created and simulated on a PC. The integrated Ethernet interface allows communication between up to nine Logo! 8 modules or SIMATIC S7 systems. With the also integrated web server, connected consumers can be monitored and controlled via WLAN or the Internet. Users can design the web pages themselves, even without HTML knowledge. Additional modules enable GSM or GPS communication as well as integration into a KNX building management system. Logo! 8 base devices are available with and without displays for various input voltages and with transistor or relay outputs (up to 10 A rated current). Expandable with additional modules to up to 24DI / 20 DQ (8 AI / 8 AQ). Integrated cloud communication. Logo! 8 can also be expanded with an external text display for meaningful messages in plain text. The background color can be chosen for visual highlights. Various Logo! power modules for power supply are also available. Logo! Soft Comfort stands for sensationally simple and fast project planning. Contact and function diagrams can be created by selecting the respective functions and their connections via drag & drop. Additionally, the entire switching program can be simulated and tested offline on a PC.
