LOGO! 12/24RCEO, logic module, SV/I/O: 12/DC 24V/relay, 8 DI (4AE)/4 DO, without display, memory 400 blocks, modularly expandable, Ethernet, integrated web server, data log, user-defined web pages, standard microSD card for LOGO! SOFT Comfort from V8.4, older projects can be run Cloud connection, MQTT in all LOGO! 8.4 basic devices The LOGO! 8 basic devices with 8 digital inputs and 4 digital outputs and their small installation width of 72 mm have many well-known functions (impulse relay, staircase automation, auxiliary contactor, time relay, etc.) integrated, which can be combined with one another in many different ways. Switching programs can be easily created and simulated on the PC. The integrated Ethernet interface allows communication between up to nine LOGO! 8 modules or SIMATIC S7 systems. The web server, which is also integrated, can be used to monitor and control connected consumers via WLAN or the Internet. The user can design the websites themselves, even without HTML knowledge. Additional modules enable GSM or GPS communication and integration into a KNX building management system. LOGO! 8 basic devices are available with and without displays for various input voltages and with transistor or relay outputs (up to 10 A rated current). Can be expanded with additional modules to up to 24DI / 20 DQ (8 AI / 8 AQ). Cloud communication integrated. LOGO! 8 can also be expanded to include an external text display for meaningful messages in plain text. The background color can be selected for visual highlighting. Various LOGO! power modules for power supply are also available.
