SIPLUS LOGO! 230RCE is based on 6ED1052-1FB08-0BA2 with conformal coating, operating temperature from -25 to +60 °C, and a start temperature of -20 °C. It features a logic module with a display, SV/E/A 115V/230V/relay, 8 digital inputs, and 4 digital outputs. It supports 400 blocks, is modularly expandable, has integrated Ethernet, a web server, and customizable data logging web pages, as well as a standard microSD card for LOGO! Soft Comfort from version 8.4, with compatibility for older projects. Cloud connectivity and MQTT are available in all LOGO! 8.4 base units. The LOGO! 8 base units, with a compact installation width of 72 mm, offer many familiar functions (pulse relay, stairwell automation, 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 with up to nine LOGO! 8 modules or SIMATIC S7 systems. With the built-in 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 units are available with and without displays for various input voltages, and with transistor or relay outputs (up to 10 A rated current). They can be expanded with additional modules to up to 24 digital inputs and 20 digital outputs (8 analog inputs and 8 analog outputs). Cloud communication is integrated. LOGO! 8 can also be expanded with an external text display for clear text messages. The background color can be chosen for visual highlighting. Various LOGO! power modules for power supply are also available.
