1747 L511 CPU Allen Bradley PLC
Allen Bradley 1747 L511 :
The Allen Bradley 1747-L511 is an SLC 5/01 Processor and part of the SLC 500 system. It is a small, easy-to-use processor with a wide range of applications including small process control, material handling, HAVC control, etc. It contains a PLC-5 processor-based advanced instruction set and can be stand-alone or distributed throughout for SCADA applications.
The 1747-L511 processor has total user memory of 1 K. It has up to 960 local digital I/O; its program scan time per keyword is 8 millisecond and it has a 2.6 millisecond I/O scan time. With a backplane current of 350 mA at 5 Volts DC and 105 mA at 24 Volts DC, it has a maximum of 3 local I/O chassis with a maximum of 30 module I/O slots in local I/O chassis. For communication, it uses DH-485 that can only send or receive messages but cannot initiate it. For programming, it supports RSLogix 500 software.
This module is not compatible with the 1746-BLM, 1746-BTM, 1746-MPM, 1746-HS, 1746-HSCE, 1746-QV, 1747-SN, 1747-SDN, or 1747-SCNR15 modules. It is intended for use in clean and dry industrial environments, with a 0-60 degree Celsius operating temperature and a 30 g operating shock. It has a battery backup for the 1747-L514 module and a capacitor backup for the 1747-L511 module, and includes red PC RUN, CPU FAULT, FORCED I/O and BATTERY LOW, LED status indicators for troubleshooting and diagnostics.
