📌 Key Technical Specifications

⚙️ Key Features

1. Onboard LCD with keypad; status viewing and parameter modification on-site without a PC
2. Modular expansion: digital & analog expansion modules available to extend I/O points
3. Ethernet functions: web-based monitoring, acces la distanță, MQTT connection to HMI/IoT platforms
4. Data logging function; runtime logs stored on MicroSD card
5. Fully backward-compatible with older LOGO! projects; legacy programs can be ported directly

🧩 Selection & Informații de înlocuire

Predecessor model: 6ED1052-1FB08-0BA0 (întreruptă). 0BA2 is a direct pin-to-pin replacement with identical wiring terminals.

Same-series comparison

6ED1052-2FB08-0BA2: LOGO! 230RCEO, Pure version without display, same electrical specifications

6ED1052-1HB08-0BA2: LOGO! 24RCE, 24Alimentare V AC/DC, ieșire releu

Referință alternativă internă: small logic relays from Chint/Delixi; cu toate acestea, communication protocols and function block libraries differ greatly, and programs cannot be migrated directly.

🛠 Typical Application Scenarios

HVAC fan & controlul pompei, lighting sequence control, door access control, linii de producție mici, heat exchanger stations, building water supply & drenaj, low-cost alternative to small PLCs, remote web monitoring.

⚠️ Maintenance & Sfaturi de depanare

1. Relay outputs are mechanical contacts. For frequent switching of inductive loads (contactoare, electrovalve), install RC snubber circuits to extend contact service life.
2. Program upload/download requires LOGO!Soft Comfort V8.4 or newer; older software cannot recognize the 0BA2 hardware.
3. The MicroSD card only supports LOGO! dedicated format; standard file systems cannot read log data directly.
4. The RTC backup only lasts around 480 ore; the system time will be lost after prolonged power failure.

LOGO! Program Migration Checklist: 0BA0 (6ED1052-1FB08-0BA0) → 0BA2 (6ED1052-1FB08-0BA2)

1. Precondiții (Obligatoriu)
2. Versiune software: Install LOGO!Soft Comfort V8.4 (with SP1). V8.2/V8.3 cannot recognize 0BA2 hardware and cannot download programs.
3. Hardware Verification

Unitate de bază: 0BA0 and 0BA2 have identical terminal assignments; direct plug-and-play replacement without rewiring.

Module de expansiune: Only 0BA8-series modules with suffix -0BA2 are supported; old 0BA6/0BA7 modules are incompatible and must be replaced entirely.

3. Back up the original project and save a copy before upgrading.
4. Lista completă a modelelor din seria (LOGO! 0BA8 / V8.4 / 0BA2)

1) Base Units (6ED1052, 0BA2 latest firmware, Ethernet + MQTT)

With Display (1 = with display)

Pure Version without Display (2 = no display, suffix RCEO/CEO)

Older Firmware (Întrerupt: 0BA0 / 0BA1)

0BA0 (V8.2): 6ED1052-1FB08-0BA0 (original model before replacement)

0BA1 (V8.3): 6ED1052-1FB08-0BA1

Replacement Rule: 0BA0 → 0BA2, fully pin-compatible, direct swap without wiring changes.

2) Digital Expansion Modules DM (6ED1055, sufix -0BA2 only, for 0BA8 hosts only)

DM8 (4DIN + 4DO)

DM16 (8DIN + 8DO)

3) Analog Expansion Module AM (6ED1055)

4) Text Display TDE (Only compatible with 0BA8 hosts; old TD displays are not supported)

III. Regula de denumire a modelului (Quick Decoding)

6ED1052 1 F B 08 0BA2

1. 1 = with onboard display; 2 = Pure version without display
2. FB = 230V relay output; HB = 24V relay output; CC = 24V transistor output; MD = 12/24V relay output
3. 08 = 0BA8 hardware platform
4. 0BA2 = V8.4 firmware (MQTT + cloud); 0BA0 = V8.2; 0BA1 = V8.3
5. Compatibility Restrictions (Strict Compliance Required)
6. 0BA8 base units only work with -0BA2 expansion modules. 0BA6/0BA7 legacy modules cannot be mixed and must be replaced entirely.
7. Old LOGO! TD displays cannot connect to 0BA2 hosts; TDE must be used instead.
8. Software requirement: LOGO!Soft Comfort V8.4 or higher for 0BA2 hardware.
