LOGO! 8.4 Logic Modules

Siemens LOGO! 8.4 Logic Modules are space-saving basic interfaces for connecting expansion modules. The modules connect up to 24 digital inputs, 20 digital outputs, 8 analog inputs, and 8 analog outputs. The LOGO! 8.4 series features an integrated display field with a parameterizable backlight, operator control panel, and EEPROM memory for control programming and setpoint values. The logic modules utilize an Ethernet interface for communication with LOGO! 8, LOGO! TDE, SIMATIC controllers, and SIMATIC panels and PCs. The basic logic modules provide an integrated web server for TD-based web pages or user-defined web pages. The Siemens LOGO! 8.4 Logic Modules perform various basic logic and special functions, including pulse edge evaluation, timer, counter, and analog function blocks.
