Information About 1747-L514
The 1747-L514 is part of the SLC 500 family and functions as a compact processor for small to medium control applications. Its design uses capacitor-backed RAM with optional EEPROM modules for non-volatile program storage, and it supports multiple instruction types including timers, counters, math, sequencers, and subroutines. This processor integrates with 1746 modular chassis, supports remote and extended I/O configurations, and communicates via DH-485 using interface converters such as the 1761-NET-AIC. Typical applications include machine control, small process automation, and legacy system expansions requiring stable scan performance and modular hardware flexibility.
Key Features:
- 4K user memory: Supports basic logic, sequencing, timing, and data handling.
- Integrated DH-485 communication: Enables programming and network connectivity.
- Supports 30 total modules: Works across up to three SLC 500 chassis.
- Optional EEPROM backup: Allows non-volatile program storage via 1747-M1/M2 modules.
- Fast scan performance: 8 ms program scan and 2.6 ms I/O scan times.
- Wide instruction support: Bit logic, timers/counters, math, moves, sequencers, and subroutines.
- Slot 0 processor: Designed exclusively for the first slot of any 1746 chassis.
- Rugged environmental design: Operates from 0–60 °C with industrial shock/vibration tolerance.
The 1747-L514 delivers the reliability and precision required for modular SLC 500-based control systems.
