Overview
The 6ED1052-1CA00-0BA0 is a Siemens LOGO! logic module — a compact programmable relay with an integrated display and keypad. It provides 6 digital inputs and 4 relay outputs, runs on a 24 V DC supply, and is rated IP20 for in-cabinet mounting on a DIN rail.
Function & operation
This LOGO! module operates as a standalone logic controller or as a smart relay in a distributed control scheme. The 6 digital inputs accept 24 V DC signals from pushbuttons, limit switches, or sensor outputs; the 4 relay outputs switch loads up to 24 V DC at 0.3 A per channel — suitable for pilot lamps, contactor coils, and small solenoid valves. The built-in display and keypad allow on-site program entry and monitoring without a PC, which is useful during commissioning or for quick logic changes on the floor.
Applications
LOGO! modules of this class are used in small automation tasks — conveyor interlocks, pump sequencing, lighting control, HVAC damper logic, and access gate control. They replace relay panels in applications where a handful of inputs and outputs, plus basic timing and counting functions, are sufficient.
