1. Model Code Decoding

2. Especificações elétricas principais

3. Hardware & Notas de fiação
4. Input terminals I1-I8 are universal AC/DC inputs matched to the 115-230 V supply rating. When I1/I2/I7/I8 are software-enabled as 0-10 V AI, these terminals shall receive voltage signals and must NOT be connected to high-voltage mains.
5. Relay outputs are potential-free contacts; common terminals can be wired to circuits of different voltage levels. Para cargas indutivas (contatores, válvulas solenóides), RC snubber circuits must be connected in parallel.
6. LAN port: For programming, remote web-based monitoring, MQTT cloud uplink; built-in web pages are accessible directly via web browser.
7. SD-Card: Importar / export programs & logs, perform firmware upgrade.

⚠️ Critical Prohibitions

Do not exceed ratings: 10 A resistive / 3 A inductive for relay outputs. Do not drive high-power motors directly. External fuses are required.

When channels are multiplexed for analog input (0-10 V), applying AC230 V will destroy input circuitry.

Classificação IP20: For cabinet-mount use only. Not for outdoor installation, condensing or corrosive environments.

4. Compatible Replacement Options

– Direct drop-in replacement: `6ED1052-1FB08-0BA2` (LOGOTIPO! V8.4, current order reference)

– Legacy compatible variant: `6ED1052-1FB08-0BA1` (V8.3, identical pin-out, backward-compatible program; older firmware lacks MQTT features)

Observação: LOGOTIPO!8.x (0BA8) base units are NOT compatible with legacy 0BA7 / 0BA6 expansion modules. Use LOGO!8-series expansions only (por exemplo. 6ED1055-1FB00-0BA2).

5. Cenários típicos de aplicação

Automação predial: controle de iluminação, fã & pump management, AVAC, auxiliary access-control logic; stand-alone simple machine control; agricultural irrigation; interlock logic for packaging machinery; IoT edge data acquisition, MQTT uplink to SCADA / cloud platforms.

❗ Excluded: Cabo Ethernet, SD-card, external fuses, expansion modules (order separately).

5.1 Building HVAC (Primary Use-Case)

1. Controle do ventilador: Exaustores, fresh-air supply-fan interlocks; scheduled start-stop, differential-pressure trigger, alarme de falha; web-based remote status visualization.
2. Controle da bomba: Domestic-water / circulation pumps with duty-standby automatic change-over, overload alarm, water-level interlocking.
3. Lighting-control system

– Scheduled lighting for workshops, underground car-parks and public corridors; PIR trigger, holiday calendar scheduling.

– Fire-alarm interlock for lighting cut-off; upload lighting status via Ethernet to central control room.

4. Air-handling unit & damper control: Damper actuators, heater simple logic; 0-10 V channels acquire temperature / humidity transmitters for basic closed-loop regulation.
5. Cooling-tower & roof ventilation: Local logic plus remote web monitoring; MQTT data upload to building BA-system.

Vantagens: No separate 24 V power supply required for 230 V operation; built-in web-server removes need for dedicated SCADA for browser-based supervision.

5.2 Stand-alone Simple Machine Control

For low-I/O machinery where full-scale PLC is not justified

1. Packaging auxiliary equipment: Conveyor start-stop interlocks, silo level detection, indicadores de alarme, timed discharging cycles.
2. Injection-molding auxiliary & cooling units: Cooling-fan / circulation-pump logic; 0-10 V temperature acquisition, fault-alarm output.
3. Air-compressor auxiliary control: Exhaust-fan, timed solenoid drain valve, aggregated fault-signal output.
4. Gate / roller-shutter / lifting-door logic: Limit-switch monitoring, interlocks, atraso de tempo, manual-auto mode switching.

⚠️ Limitation: Máx.. 3 A inductive rating for relay contacts; use intermediate relays for large contactor coils. Not applicable for high-speed pulse-based motion control.

5.3 Agricultura & Tratamento de Água

1. Greenhouse simplified automation: Fã & shade-blind actuation; 0-10 V temperature-humidity acquisition; timed irrigation solenoids; MQTT upload to IoT platform.
2. Small-scale wastewater / reclaimed-water equipment: Pump rotation scheduling, high-low level interlocks, timed chemical-dosing, alarm outputs.
3. Fountains & water-feature installations: Cyclic multi-pump sequencing, fault-alarm logic.

5.4 Electrical Cabinet & LV Panel Auxiliary Logic

1. Low-voltage switchgear auxiliary logic: Bus-coupler interlocking, cabinet cooling-fan control, cabinet-door status acquisition, collective fault-alarm output.
2. VP / energy-storage auxiliary cabinets: Cabinet-heater / dehumidifier & cooling-fan temperature-driven / timed control; alarm telemetry over Ethernet.
3. UPS emergency-power auxiliary logic: Mains-failure detection, switching logic, audible-visual alarm outputs.

5.5 IoT Edge Acquisition (V8.4-Exclusive MQTT Feature)

Core enhancement versus older V8.3 (-0BA1 firmware):

1. Acquire digital status and 0-10 V analog measurements; transmit via MQTT to private / public cloud servers (por exemplo. Alibaba Cloud).
2. Operate as Modbus-TCP slave for connection to HMI / host supervisory systems. Built-in web-server for PC / mobile-browser status access without dedicated software.
3. Micro-SD-card data logging: record temperature, runtime timestamps; export CSV files for maintenance review.

❌ Non-Applicable Scenarios (Selection Pitfalls)

1. High-speed counting, pulse-output, servo motion control: Not supported by LOGO!.
2. Large I/O quantity: Native 8DI /4DO; maximum expandable to 24DI /16DO. For larger systems select S7-1200 PLC.
3. Frequent switching of heavy inductive loads: Limited mechanical relay contact life; use transistor-output variants for high-cycle applications.
4. Hazardous / explosive-risk zones: IP20 unit must be installed inside certified explosion-proof enclosures; cannot be mounted directly in Zone1/Zone2.
5. High-precision PID closed-loop control: Only basic PID function-block available; use standard PLC for demanding closed-loop performance.

Typical System Configuration Examples

Temperature acquisition: Multiplex I1 as 0-10 V AI for connection to temperature transmitter.

Contactor driving: LOGOTIPO! relay output → intermediate relay → contactor coil.

Monitoramento remoto: RJ45 LAN to local network; access embedded web-server via browser.

I/O expansion: 6ED1055-1FB00-0BA2 (230 V relay expansion module).

Critical Limitations (Selection Constraints)

1. Relay outputs are not suitable for high-cycle switching; intermediate relays must be used for heavy loads.
2. When channels are configured for 0-10 V analog input, AC230 V mains must never be connected, as input hardware will be destroyed.
3. No native high-speed counter, pulse-output or motion-control functions.
4. Only LOGO!8-series expansion modules (order suffix-0BA2) are compatible; legacy 0BA7 / 0BA6 expansions will not work.
5. No internal short-circuit protection; external fuses are required for all relay-output circuits.
