Product Overview
The Siemens 6AG1055-1HB00-7BA2 is recorded as an expansion module within the SIPLUS LOGO! series. It builds upon the base model 6ED1055-1HB00-0BA2 with specialized environmental protections.
This device supports power supply and I/O configurations at 24 V/24 V/relay. It includes two medium-power outputs and four digital inputs alongside four digital outputs.
Technical Review Notes
- The module operates within a standard temperature range of -40 to +70 degrees Celsius. Startup functionality is confirmed down to -25 degrees Celsius for cold conditions.
- Conformal coating is applied to protect internal components from moisture and corrosive agents. This ensures durability in challenging industrial settings where standard units might fail.
- Input types are specified as AC/DC/NPN for the LOGO! 8 series integration. This flexibility allows connection to various sensor types commonly found in automation projects.
- Power supply requirements are listed as 24 V for both logic and I/O circuits. The relay outputs provide switching capability for connected loads without direct electrical isolation issues.
- Physical dimensions are recorded at 9.6 x 5.7 x 7.1 centimeters. The compact form factor allows for efficient mounting within control cabinets or distribution boxes.
- Net weight is documented at 0.175 kilograms. This light mass facilitates easy handling during installation and reduces the overall load on mounting structures.

Parameter Review
- Verify the 24 V DC power supply requirement matches your existing cabinet infrastructure. Ensure voltage stability to prevent module malfunction during operation.
- Confirm that the AC/DC/NPN input types align with your sensor specifications. Mismatched input types may require additional signal conditioning hardware.
- Check the relay output capacity against your load requirements. Exceeding the medium-power rating could damage the output contacts over time.
- Assess the -40 to +70 degree Celsius range against your site conditions. Temperatures outside this window may affect performance or longevity.
Catalog Classification
Image & Label Review
- Images typically show the front panel with terminal blocks for wiring connections. These terminals correspond to the digital input and output channels described.
- Side views often highlight the DIN rail mounting clip mechanism. This allows secure attachment to standard 35 mm rails in control panels.
- Labeling on the unit displays the full part number and voltage ratings. These markings assist in quick identification during maintenance or troubleshooting.
- Internal photos may reveal the conformal coating on the circuit board. This protective layer is critical for the module's extended environmental rating.

Inquiry Preparation
- Prepare your project documentation specifying the required quantity and delivery location. Include any special handling instructions for sensitive electronic components.
- List the target application environment details such as humidity or chemical exposure levels. This helps confirm the suitability of the conformal coating.
- Provide schematic diagrams showing the intended wiring configuration for inputs and outputs. Clear diagrams reduce ambiguity in technical discussions.
- Specify the desired communication protocol if integrating with other PLC systems. Although this is an expansion module, system-level integration matters.
Category Context
This item resides within the PLC CPUs & Controllers category structure. It serves as an auxiliary component rather than a primary processing unit.
It complements main LOGO! controllers by expanding I/O capabilities. This allows larger automation tasks to be managed with a single controller platform.
Review Notes
- Ensure all technical parameters match your specific engineering requirements before submission. Discrepancies can lead to integration challenges during commissioning phases.
- Cross-reference the conformal coating specifications with your industry standards. Some sectors require specific certification levels for environmental protection materials.
- Review the power consumption figures against your total cabinet load budget. Adding multiple expansion modules can significantly impact overall energy usage.
- Confirm the physical dimensions fit within your recorded DIN rail space. Clearance requirements for ventilation and cable management must also be considered.
