8 DI / 4 DO relay logic module for small automation tasks
The Siemens 6ED1052-2HB00-0BA6 is a LOGO! 24RCO logic module — a spare-part designation for a compact controller with 8 digital inputs and 4 relay outputs, powered by UC 24 V (AC or DC). It is developed in accordance with IEC 61131 and rated for use in residential areas per limit class B. The relay outputs handle up to 10 A resistive or 3 A inductive loads, so it directly drives small contactors, solenoid valves, or indicator banks without an interposing relay. The 80-hour power reserve holds the program and retentive data through a supply interruption — relevant for process lines where a brownout shouldn't lose the machine state.
The 90 mm height and 55 mm depth fit standard enclosures. IP20 protection means it is intended for a clean, dry cabinet. Rated for 0 °C to 55 °C ambient, with AC supply tolerance from 47 Hz to 63 Hz and DC tolerance from 20.4 V to 28.8 V. The module carries CE, UL, CSA, FM, and marine approvals — so it passes inspection for most industrial panels, building services, and shipboard auxiliary systems.
Sourcing and lifecycle note
Listed as a current-production spare part. No external short-circuit protection is integrated — the installation must provide fusing or a miniature circuit breaker upstream.
