Overview
LOGO! 8 covers the gap between relay logic and a PLC: pump alternation, lighting and HVAC control, small conveyors and test rigs. The 12/24RCE version runs on 12 or 24 V DC, has four analog-capable inputs and relay outputs rated 10 A, and includes an Ethernet port with a web server for monitoring from a phone or browser. Expansion modules add up to 24 DI, 20 DO, 8 AI and 8 AO. Programming in LOGO! Soft Comfort is function-block based and takes an afternoon to learn.
Key features
- 8 digital inputs, 4 of them usable as 0–10 V analog inputs
- 4 relay outputs, 10 A resistive
- Ethernet with web server, S7 communication to SIMATIC CPUs, Modbus TCP
- Integrated display and keypad; optional LOGO! TDE text display
- Clock, 400 function blocks, data logging to microSD
Typical applications
- Building and utility automation
- Pump alternation and tank control
- Small machine control
- Lighting and HVAC
