Siemens LOGO! 8 Expansion Module, 24 V ac/dc Relay, 4 x Input, 4 x Output Without Display

Different types of digital expansion modules are available to suit 5th and 6th generation LOGO! controllers
They connect to the right hand side of the base unit or preceding expansion module via an integral bus connector
Expansion modules of different types, including analogue and communications modules, can be mixed giving LOGO! the ability to have different low input and output voltages. (Mechanical interlocking prevents mains voltage and low voltage units being mixed)
Inputs/Outputs - DM8 series: 4
Dimensions - DM8 series: H: 90mm, W: 36mm, D: 55mm

Siemens LOGO! 6 Series

Siemens LOGO! 6 Series brings you additional features aimed at keeping the LOGO! At the forefront of this technology. The new generation LOGO! 0BA6 features yet another decisive advantage, the possibility to connect an extra text display without communication module. Proven to be a highly convenient for the projecting and display of operator relevant messages. The text display has been precisely optimized to the needs of a logic module and can be projected with the same function block as the internal display. Moreover, the performance of the basis module now enhanced by more than 50 percent to 200 function blocks. Thus, even more applications can be replaced through more cost-effective LOGO! Configurations, and savings potential can be tapped, Major improvements over previous LOGO! Units include:

• LOGO! TD device directly connectable to all 0BA6 basic modules.
• Display with adjustable permanent backlight (on-board and/or TD).
• Up to 50 message text blocks (on-board and/or TD).
• New integrated PWM functions.
• Simple bar-graph functionality.
• Text-ticker functionality.
• 4 Analogue inputs (0-10V) - instead of 2.
• 4 (5 kHz) fast counter-inputs - instead of 2 (2 kHz).
• Analogue output 0 mA to 20 mA or 4 mA to 20 mA.
• Ten different on-board languages (GE, EN, FR, IT, ES, CHN, JAP, TR, RUS, and NL).
