Display, displayless and preceding-generation high-voltage relay controllers.
Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 are LOGO! 230 RCE base modules for 115/230 V AC/DC control circuits. Each record provides eight digital inputs and four relay outputs, while the 2FB08-0BA2 execution omits the local display and keys.
At the panel interface, Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 route line-voltage input states into the LOGO! program and switch separately supplied loads through relay contacts. Input commons, output protection and load inrush must therefore be planned from the wiring diagram rather than inferred from the 230RCE family label.
Software generation separates Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1. The -0BA2 articles belong to LOGO! 8.4; -0BA1 is an 8.3 record, so project features and device selection must match the exact suffix before transfer.

Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 combine line-voltage sensing with relay switching; input reference and output load behavior must be evaluated separately. Commissioning should separate the line-voltage input path, LOGO! program state and externally powered relay-load path so one observation is not mistaken for proof of the whole circuit.
Verify the configured supply and the input common before energizing Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1. A lit input requires the documented voltage path, not merely conductor continuity. Record the terminal number and input common on the cabinet drawing, then compare the measured line voltage with the online input state before changing logic.
Test the connected load on Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 with inrush included. Contact behavior depends on the load category as well as steady current. Fix the physical expansion order in the project file and label each added module so later service work does not shift addresses silently.
Keep LOGO! 8.4 and 8.3 project functions separate when working with Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1. After download, test local access and the Ethernet service route separately; a reachable device is not proof that every relay circuit is complete.
Troubleshoot Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 from the supply through the input state, program logic and relay load instead of replacing the base module after one missing output. Use a repeatable evidence chain—terminal measurement, device indication, online state and load response—when diagnosing the base module.
Measure the base-module supply first, then compare the physical input and program state of Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1. If the measured input voltage is correct but the online state is wrong, inspect the input common, selected terminal and configured address before editing the program.
Use the documented external protection for every relay load connected to Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1; the relay contact is not a substitute for branch protection. When program logic energizes an output, inspect the relay indication and the external contact supply as separate checkpoints.
Save event time, input state, program version and exact article for Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 before power cycling. Repeat the test under the real load and record inrush or suppression behavior so an intermittent field fault is not hidden by an unloaded check.
Siemens 6ED1052-1FB08-0BA2 / 6ED1052-1FB08-0BA1 include the local display and keys, while Siemens 6ED1052-2FB08-0BA2 is displayless. Match the generation and operating method, not only the 230RCE family name.
Measure the selected 115/230 V supply against the documented input common directly at Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1, then compare the terminal state with the online program state.
The relay contacts of Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 use an external load circuit. Check that circuit's supply, protection, return and inrush instead of assuming the relay indication delivers load power.
Review all LOGO! 8.4 functions used by Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 before targeting the 8.3 Siemens 6ED1052-1FB08-0BA1 record; do not force transfer from the family name.
Record steady current, inrush, switching frequency and suppression for every load driven by Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1, then compare them with the relay limits.
Include the complete Siemens 6ED1052-1FB08-0BA2 / 6ED1052-2FB08-0BA2 / 6ED1052-1FB08-0BA1 article, generation, program, IP data, expansion order, terminal schedule and relay-load list.
