Overview
The 6ED1053-1HB00-0BA1 is a Siemens LOGO!24RCL logic module with integrated display and real-time clock, providing 12 digital inputs and 8 relay outputs rated at 8.0 A maximum output current. It operates on a 24 VDC or 240 VAC supply and is housed in a 126 x 90 x 57 mm enclosure for standard DIN-rail mounting.
Function & operation
This LOGO! module executes user logic from a 56-block memory, handling basic control tasks such as interlocks, timers, counters, and clock-driven sequences. The 12 digital inputs accept 24 VDC signals from pushbuttons, limit switches, or proximity sensors; the 8 relay outputs switch loads up to 8.0 A total, suitable for contactors, solenoid valves, and indicator lamps. The built-in display and keypad allow on-site program editing and status monitoring without a PC. The real-time clock enables time-switching functions — lighting schedules, HVAC staging, or equipment run-time limits. The 0 to 55 °C operating range covers most cabinet environments; the IP20 rating restricts installation to clean, dry enclosures.
Applications
LOGO! modules of this class are used in small-scale automation — standalone machine control, conveyor interlocks, pump sequencing, lighting control panels, and HVAC zone controllers. They replace multiple timers and relays in a single DIN-rail package, simplifying wiring and panel layout.
