1747-L553 SLC 64K Controller PLC Module

Overview

1747-L553 is the SLC 5/05 model processor module in the SLC 500 series. It has the largest 64KB memory in the SLC 5/05 series and is equipped with battery backup RAM (adaptive to 1747-BA battery). The storage can also be expanded through the 1747-M13 memory module, which can meet the needs of complex program writing and large data storage; the program scan time is up to 0.9 milliseconds / Thousands, the I/O scan time is 0.225 milliseconds, ensuring efficient execution of control instructions.

FAQ:

1.What are the differences in performance and functionality between different versions of 1747-L553 (such as version A, version C)?

Versions A and C of 1747-L553 are the same model processor modules of the SLC 5/05 series. Their core control performance and basic functions are highly consistent. The differences are mainly concentrated in Ethernet speed, firmware adaptability and hardware detail optimization.
In addition, there is no difference in core basic parameters. For example, both are equipped with 64K user memory, support 4096 discrete input/output points and 480 analog I/O points. The program scan time is 0.9 milliseconds/thousands. They are also compatible with RS-232 interface and communication protocols such as DH-485 and DF1. Up to 64 device communication connections can be established simultaneously, which can meet the basic control needs of medium and large industrial automation scenarios.

2.Which SLC 500 series racks are the 1747-L553 compatible with? What are the special requirements for the backplane model?

1747-L553 can be adapted to the mainstream 1746 series standard racks of this series, and there are no special compatibility restrictions on backplane models. It only needs to match the SLC 500 series specifications:

1. Adaptation rack (1746 series)

Model: 1746-A2 (2 slots), 1746-A4 (4 slots), 1746-A7 (7 slots), 1746-A10 (10 slots), 1746-A13 (13 slots)

Adaptation scenarios: Covering small to large control requirements, selected according to the number of modules

2. Backplane requirements

Core: Compatible with SLC 500 series racks with built-in backplane, no dedicated model required

Power supply: Rack backplane default matching module 5VDC 1A/24VDC 175mA (C version) power supply standard

Extension: can be indirectly adapted to the 1771 series universal I/O chassis backplane (such as 1771-A4B), and multi-rack connections require controlled spacing
