1747-L543| Allen-Bradley | Processor Unit
Description
The 1747-L543 is a high-performance processor in the SLC 500 modular hardware style series. It supports advanced programmable logic control with powerful ladder logic programming, up to 3840 I/O points, and multiple communication channels. The processor includes battery-backed RAM, a keyswitch for operation modes, and adheres to US, Canadian, and European safety standards.
Features
- Advanced math functions: trigonometric, PID, exponential, floating-point.
- Indirect addressing and logical ASCII addressing.
- Flash PROM for firmware upgrades.
- Optional flash EPROM memory module.
- Keyswitch modes: RUN, REMote, PROGram (clear faults).
- Battery-backed RAM for data retention.
- UL listed, CE compliant, C-Tick marked.
Technical Specifications
-
Power Consumption:
- 5V dc: 1.000 A
- 24V dc: 0.000 A (Processor only)
-
Total Power Supply Capacity:
- For Chassis with this processor, the 1746-P4 power supply is recommended, providing 10 A at 5V dc and 2.88 A at 24V dc.
-
Heat Dissipation:
- Total Watts: 4.00 W
-
Memory Module Compatibility:
- 1747-M1: 1 K User Words EEPROM
- 1747-M2: 4 K User Words EEPROM
- 1747-M5: Adapter Socket
-
Battery Backup:
- Lithium battery provides backup for CMOS RAM.
- Red BATTERY LOW status indicator alerts when the battery voltage falls below a threshold level.
- Battery can be replaced while the processor is powered.
-
Communication Channels:
- DH-485, DF1, or ASCII Channel 0
- DH-485 Channel 1
-
Status Indicators:
- RUN (Color: green): On (steady) - The processor is in the Run mode.
- FLT (Color: red): Flashing (at power up) - The processor has not been configured.
- FLT (Color: red): Flashing (during operation) - The processor detects a major error.
- FLT (Color: red): On (steady) - A fatal error is present (no communication).
- FLT (Color: red): Off - There are no errors.
- Additional indicators: FORCE, DH+, RS232, BATT, RUN REM PROG
-
Operating System:
- Supports multi-point list functionality (SLC 5/04 OS302 processor or later).
-
Installation Instructions:
- Always turn off power before removing the processor or inserting/removing the memory module.
- Memory modules are mounted in carriers or have connectors that are keyed to prevent improper installation.
- Handle memory modules by the ends of the carrier or edges of the plastic housing to avoid damage from skin oil, dirt, and electrostatic charges.
