SIEMENS 6ED10551HB000BA2 I/O Module 24V AC/DC 4 In 4 Out

SKU CH-QB5Q-C9716

Input/output module provides four 24 V AC/DC inputs and four outputs with 200 mA rating and screw-clamp terminals on DIN rail

  • TypeIndustrial Electrical Controls & Automation
  • 4 digital inputs expand local control
  • 4 digital outputs drive external loads
  • 24 V AC/DC supply fits common panels
  • 200 mA rating suits low-power circuits
  • DIN-rail mount with screw-clamp wiring

Application fit

The SIEMENS 6ED10551HB000BA2 is a 24 V AC/DC input/output module with four digital inputs and four digital outputs. It expands a compatible LOGO! base unit for small-scale automation tasks such as building services, machine control or process monitoring. The screw-clamp terminals and DIN-rail mounting suit panel builders who need a compact, fixed-wiring solution.

Compatibility check

Verify that the existing controller is one of the listed LOGO! base units (6ED10521CC010BA8, 6ED10521HB000BA8, 6ED10521MD000BA8, 6ED10522CC010BA8, 6ED10522HB000BA8 or 6ED10522MD000BA8) or the 6ED10580BA080YA1 variant. Confirm the control circuit can supply 24 V AC or DC and that the 200 mA per output rating covers the connected actuators. Ensure DIN-rail space and screw-terminal wiring match the panel layout. Builders needing more than four inputs or outputs, or a different voltage level, should select another module.

Thermals and power

The module draws its operating power from the 24 V supply and each output can switch up to 200 mA, so total load current determines heat dissipation inside the enclosure. With no moving parts and a passive design, acoustic noise is negligible in normal operation. Plan cabinet ventilation to handle the combined dissipation of all mounted modules under full-load conditions.

Questions about this item

What comes in the box and do I need to buy a base unit separately?

The module includes screw-clamp terminals for wiring. A compatible LOGO! base unit such as the 6ED10521CC010BA8 or 6ED10522HB000BA8 must be purchased separately to provide power and the back-plane connection.

Which version should I choose if I need 24 V AC/DC power and four inputs plus four outputs?

This 6ED10551HB000BA2 is the only variant listed with 24 V AC/DC supply, four digital inputs and four digital outputs rated at 200 mA each.

What does the 200 mA current rating mean when the module is installed on a DIN rail?

Each of the four outputs can switch up to 200 mA at 24 V AC/DC, so the total switched load across all outputs must stay within that per-channel limit when mounted on a standard DIN rail.
