Information About 1747-L514

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 adapters 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 are 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-M1 With 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 the program to the non-volatile memory, the 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.
