Description

The Allen-Bradley 1747-L514 is an SLC 500 processor unit. This module is also termed as an SLC 5/01 controller which is a single slot width controller. It mounts to the slot 0 of any 1746 modular chassis. It comes with a 4K user memory and embedded DH-485 communication interface.

The 1747-L514 is designed for use in small and medium automation requirements. It is capable of controlling a maximum number of 30 I/O modules which can be distributed up to a maximum of 3 1746 chassis. It supports implementation of extended I/O and remote I/O chassis using a variety of supported communication adapter by this SLC 500 controller.

The 1747-L514 has an electrical current load of 0.090 at 5VDC. It has a minimum power consumption of 1.75 Watts. The embedded DH-485 port supports use of the 1761-NET-AIC or the Advanced Interface Converter (AIC) module. Additionally, the memory tables of the SLC 5/01 is accessible using the Allen-Bradley Data Table Access module (DTAM).

The 1747-L514 may be installed with an optional non-volatile memory. Non-volatile memory are in the form of Electrically Erasable Programmable Read-Only Memory (EEPROM). Compatible EEPROM are 1747-M1with 1K User Words EEPROM, 1747-M2 with 4 K User Words EEPROM with a 1747-M5 memory module adapter socket. EEPROM modules may be used to burn programs stored in the built-in memory which is a Random Access Memory (RAM). By burning program to the non-volatile memory, user program may be automatically loaded once the controller is power cycled.

It uses the 1747-BA lithium battery assembly with a 30-minute capacitor life and a lithium battery with a 2-year lifespan for backup power for the standard RAM. The 1747-L514 has a maximum bit execution time of 4µs and an overall module scan time of 8ms/K. During a temporary power loss, the program scan on the module can take from 20ms to 3s depending on the power supply that is loading. It comes with a base DH-485 communication capability which can only act in a slave capacity (Receiving) in the programming channel. The 1747-L514 has an ambient operating temperature range of 0-60°C (32-140°F) at 5-95% non-condensing relative humidity range, and it is designed to sustain an operational shock of 30G, and a vibration of 2.5G at 57-2000Hz. The 1747-L514 is C-UL, UL, and CE-certified, and it offers a NEMA standard ICS 2-230 industrial noise immunity.

 

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, HVAC control, etc. It contains a PLC-5 processor-based advanced instruction set and can be stand-alone or distributed throughout for SCADA applications.(http://www.weikunfadacai1.com)

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.

 

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.

 

The 1747-L511 is the entry-level processor of the modular style hardware of SLC 500. This processor has the most basic features having a 1KB memory which makes it capable of handling up to 3940 IO signals. However, this module does not support implementation of Remote I/O topology. It may only be expanded of a maximum Three (3) SLC chassis of any type or a maximum 30 IO slots. This processor is UL listed to US and Canadian Safety Standards, CE compliant, and C-Tick marked.

This processor has memory back-up option of Electrically Erasable Programmable Read-Only Memory (EEPROM) which is basically a non-volatile memory, This non-volatile memory may be used to permanently store a the Programmable Logic Controller (PLC) program to prevent accidental deletion that is commonly caused by power surges and draining of the battery. It may also be configured to automatically load the user program each time a power cycle is initiated.

The integrated memory of this processor is Random Access Memory (RAM) that is maintained by a Lithium battery that can last up to Two (2) years. The battery charge is indicated by the Battery Low LED light which activates when the battery voltage is low. This battery is replaceable with 1747-BA however, do not replace the battery with the power removed. The processor must be actively powered when replacing otherwise, the user programs gets deleted.

 

This processor has other installed LED status indicators aside from the battery indicator. These indicators include Run, CPU Fault, and Forced I/O.
