6ED1052-1MD08-0BA1 — Siemens LOGO! 8 Logic Module
Siemens LOGO! 8 is the intelligent logic module that replaces the wiring of timer relays, counter relays, and auxiliary contactors in simple control applications with a programmable device handling the same logic in software. The LOGO! 8 base unit provides 8 digital inputs (4 switchable as 0–10 V analog), 4 relay outputs, and an integrated 6-line LCD display with backlit keypad — covering control requirements of most simple machine tasks: stairwell lighting timers, pump alternation, irrigation scheduling, tank level control, and heating/ventilation interlocking, all without PLC programming knowledge beyond understanding the available LOGO! function blocks.
The LOGO! 8.SF Ethernet model adds a 10/100 Mbit port for web server monitoring, remote parameter access from any browser without additional software, and Modbus TCP communication to BMS and SCADA platforms. A facility manager in Riyadh can view the LOGO!'s current I/O states and parameter values in any web browser on a tablet or smartphone without VPN or specialist software — a practical remote monitoring capability for the geographically dispersed applications typical in Saudi Arabia's large residential and commercial estates. Up to 24 expansion modules extend a single LOGO! 8 to 64 I/O points without stepping up to a full S7-1200 PLC architecture.
In Saudi Arabia, the LOGO! 8 is the most cost-effective Siemens automation device for light control, simple machine sequencing, and building services applications. Electrical contractors, building services companies, and small OEM machine builders across the Kingdom use LOGO! for stairwell lighting timers, mosque lighting scene control, garden irrigation, compound gate control, small pump alternation, and HVAC auxiliary control. The on-device display and keypad allow facilities maintenance personnel to adjust timer settings and thresholds directly without a laptop — a significant operational advantage for facilities management companies maintaining hundreds of dispersed buildings.
Razz Middle East stocks LOGO! 8 base units and expansion modules for immediate delivery throughout Saudi Arabia with LOGO! Soft Comfort programming support.

Key Features & Benefits
- Graphical LOGO! Soft Comfort programming with function-block drag-and-drop replaces timer relay wiring in under 30 minutes for most simple applications, requiring no PLC programming knowledge from the installer.
- Ethernet web server on LOGO! 8.SF provides remote monitoring of all I/O states from any web browser on a tablet or smartphone without VPN — useful for facilities management of dispersed Saudi estate and building sites.
- Modbus TCP on the LOGO! 8.SF enables integration with BMS and SCADA platforms for remote monitoring and parameter adjustment of LOGO!-controlled plant rooms and utility systems.
- On-device display and keypad allows adjustment of timer settings, analog thresholds, and counter presets directly on the installed device without a laptop — essential for maintenance personnel managing dispersed sites.
- 24-module expansion extends a single LOGO! to 64 I/O points, covering multi-zone irrigation controllers and small machine control applications exceeding the base unit capacity.
- Integrated data logging to an SD card records up to 10,000 entries of analog values and timer events, providing a maintenance history log for standalone installations without an external data logger.
- Transistor output LOGO! variants (24CE) provide high-speed switching up to 5 kHz for simple step-direction stepper motor control and frequency output applications.
Industrial Applications in Saudi Arabia
- Stairwell and corridor lighting timer control in apartment towers and commercial buildings across Saudi Arabia, replacing multiple individual timer relays with a single programmable device adjustable for seasonal lighting time changes.
- Mosque and prayer hall lighting scene control in Saudi commercial and residential developments, managing multi-zone lighting scenes for prayer times, cleaning, and general illumination.
- Garden and landscape irrigation scheduling for residential compounds and hotel grounds, where the Ethernet web server allows remote irrigation programme adjustment without site attendance.
- Small pump alternation control for dual-pump booster sets in apartment buildings, where LOGO! alternates duty and standby pumps, counts running hours, and triggers alarms on pump failure.
- HVAC auxiliary control in commercial plant rooms — AHU contact interlocking, fan thermal protection, damper sequencing — where LOGO! handles simple interlock logic without requiring an S7-1200 PLC.
- Compound gate and car park barrier control with entry/exit timers and loop detector logic at Saudi residential compounds and commercial properties.
- Small industrial machine sequencing for workshop tools and CNC machine auxiliary systems in Saudi small-scale manufacturing units, where LOGO! provides start/stop, guard interlock, and alarm output logic.
