More Information

Overview Manuals Performance Communication Installation Environment

Features:

  • Provides 4K instructions of user memory for the stored SLC 500 control program.
  • Supports up to 4096 inputs and 4096 outputs in a modular SLC 500 configuration.
  • Uses an integrated DH-485 port for programming and network communication.

1747-L524 is the 4K SLC 5/02 processor configuration for a modular 1746 SLC 500 system. It is intended for applications that require expanded I/O capacity while retaining DH-485 communication.

The processor repeatedly scans the stored ladder program, updates the chassis I/O image, and coordinates installed modules through the SLC backplane. Its typical program scan is 4.8 ms/K, and its typical I/O scan is 1.6 ms.

Confirm processor placement in slot 0, the required I/O count, chassis and power-supply capacity, DH-485 node settings, compatible 1746 modules, and the stored application before installation.

Availability: OEM-discontinued; contact Apter Power for quotation, documentation, and sourcing support.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • 1747-L541 provides 16K words of total memory: 12K words for program or data and 4K words reserved for data.
  • The processor supports up to 4096 inputs and 4096 outputs, with a typical program scan time of 0.9 ms/K and a typical I/O scan time of 0.225 ms.
  • It supports up to three local chassis and 30 local module slots, with a backplane load of 1.0 A at 5V DC and 200 mA at 24V DC.
  • 1747-L524 provides an integrated DH-485 port for programming and communication on a compatible SLC 500 network.
  • The SLC 5/02 processor can initiate communication messages as part of the configured control application.
  • The DH-485 channel supports data exchange with compatible processors, programming devices, and network interfaces.
  • 1747-L524 is installed in processor slot 0 of the local 1746 SLC 500 chassis.
  • The processor supports a maximum of three local chassis and 30 local module slots.
  • Its backplane load is 350 mA at 5V DC and 105 mA at 24V DC for chassis power-supply calculations.
  • The specified operating temperature range is 0 to 60 °C (32 to 140 °F).
  • The specified operating relative humidity range is 5 to 95 percent without condensation.
  • The modular SLC 500 hardware specification lists vibration acceleration of 2.5 g from 57 to 2,000 Hz.
Description
1747-L524 is an Allen-Bradley SLC 5/02 processor for modular SLC 500 control systems. It provides 4K instructions of user memory and can address up to 4096 inputs and 4096 outputs for local or scanner-based remote I/O configurations.

The processor supports up to three local chassis and 30 module slots. Its typical program scan time is 4.8 ms/K, its typical I/O scan time is 1.6 ms, and its backplane load is 350 mA at 5V DC plus 105 mA at 24V DC.

The integrated DH-485 interface supports programming and data exchange, and the SLC 5/02 processor can initiate communication on the DH-485 network. This distinguishes its communication capability from the receive-and-reply behavior of the SLC 5/01 processor.

Before installation, confirm memory capacity, I/O addressing, scanner requirements, chassis power, DH-485 settings, and the stored application program for the target SLC 500 system.
