LOGO! 12/24RCEO, logic module, PS/I/O: 12/24VDC/relay, 8 DI (4 AI)/4 DQ, without display, memory 400 blocks, modular expandable, Ethernet, integrated web server, data log, user-defined web pages, standard microSD card for LOGO! Soft Comfort V8.3 or higher, older projects executable cloud connection in all LOGO! 8.3 basic units The LOGO! 8 basic units with their 8 digital inputs and 4 digital outputs and an installation width of just 72 mm integrate a host of familiar functions (current impulse relay, automatic staircase timer, contactor relay, time relay, etc.) which can be combined with one another in many different ways. Switching programs can be created and simulated easily on the PC. Depending on the integrated Ethernet interface, communication between as many as nine LOGO! 8 modules or SIMATIC S7 systems is possible. The web server is also integrated and can be used to monitor and control connected loads over WLAN or Internet. Users can design web pages themselves, even without knowledge of HTML. GSM or GPS communication as well as integration in KNX building management systems is possible using additional modules. LOGO! 8 basic units are available with and without displays for different input voltages as well as with transistor or relay outputs (up to 10 A rating). Can be expanded with additional modules for up to 24 DI / 20 DQ (8 AI / 8 AQ). Cloud communication integrated. LOGO! 8 can also be expanded with an external text display for clearly visible messages in plain text. The color of the backlit display can be selected for optical highlighting. A variety of LOGO! power modules are also available for power supply.
