1747-M11 Advantages
The Allen‑Bradley 1747‑M11 Memory Module stands out from comparable PLC memory accessories in several key areas.
Battery‑free non‑volatile EEPROM storage. The Allen‑Bradley 1747‑M11 Memory Module uses EEPROM technology, the Allen‑Bradley 1747‑M11 Memory Module retains stored program content without backup battery, eliminating program‑loss risk caused by CPU battery exhaustion.
Automatic power‑on program restore function. After system power loss and subsequent power‑on, the Allen‑Bradley 1747‑M11 Memory Module can automatically transfer the stored ladder logic program into SLC‑500 CPU RAM, shortening equipment recovery time after fault events.
Compact front‑mount plug‑in design. The Allen‑Bradley 1747‑M11 Memory Module plugs directly into the dedicated front‑side memory connector of compatible SLC‑500 CPUs, occupying no additional chassis slot resources of the SLC‑500 rack.
Program duplication convenience. The Allen‑Bradley 1747‑M11 Memory Module supports program copy between CPU and memory module, which assists users to duplicate identical application programs for multiple SLC‑500 controller units.
Native Allen‑Bradley 1747 SLC‑500 integration. As a factory‑original Allen‑Bradley 1747 series component, the Allen‑Bradley 1747‑M11 Memory Module works natively with supported SLC‑500 CPU firmware without extra configuration tools.
Simple status visual feedback. The Allen‑Bradley 1747‑M11 Memory Module is equipped with status LED indicator, helping technicians to judge read/write working state of the Allen‑Bradley 1747‑M11 Memory Module during backup‑restore operations.
1747-M11 Applications
