What the LOGO! 12/24RCE Covers — and What It Doesn't
The 6ED1052-1MD00-0BA7: Eight digital inputs are on board, four of which can be configured as analog inputs (0 to 10 V). That means a single unit can read a 0-10 V sensor (pressure, level, temperature) without an add-on analog module — useful for small standalone machines where every expansion slot costs panel space. The four relay outputs are rated 10 A resistive and 3 A inductive. The 10 A figure covers resistive loads like heaters or indicator lamps; the 3 A inductive rating is the one that matters for small contactors, solenoid valves, or motor starters. The relay contacts handle the inrush without external interposing relays for most fractional-horsepower loads.
Supply, Retention, and Environmental Limits
Runs on 12 or 24 VDC (permissible range 10.8 to 28.8 V DC). The wide tolerance means a sagging 24 V bus from a battery-backed supply or a long cable run won't drop the CPU. No internal short-circuit protection — an external fuse or circuit breaker on the supply line is mandatory per the spec. Integrated power reserve holds the program and retentive data for 480 hours without external power — no battery to replace or monitor. The display is on the front panel for local status and parameter changes without a programming cable. Operating temperature range is 0 °C to 55 °C. The 0 °C floor means no operation below freezing; if the panel sees sub-zero startup, a heater or relocation is needed. IP20 protection — keep it inside a closed enclosure, not on the open machine frame.
Approvals and Interference Class
Carries CE, UL, CSA, FM, and marine approvals — covers industrial panels destined for North America, Europe, and shipboard installations. Radio interference suppression meets EN55011 Limit Class B, so this module can be used in residential or light-commercial environments without additional filtering. Developed in accordance with IEC 61131, the standard for PLC programming languages. The 400-block memory handles ladder, function block, and structured text for mid-size logic sequences — think packaging machines, conveyor interlocks, or pump sequencing.
