ALLEN BRADLEY 1756-L1 PLC module programmable logic controller Allen-Bradley 100% Brand New Original

The Allen-Bradley 1756-L1 is a ControlLogix 5550 controller. It can support up to 250 connections and weighs 0.28 kilograms or 10.0 ounces. This particular controller has a 64 Kilobytes user memory. Installing the 1756-L1 is installed directly into any slot available in the chassis and multiple controllers can be installed in any other slot within the same chassis. These controllers that belong to the same chassis, may communicate communicate with each other across the backplane as well as operate independently. The 1756-L1 has the capacity to communicate across DeviceNet, RS-232-C (DF1/DH-485 protocol), ControlNet, DH+, and EtherNet/IP networks. Note that it does not have a nonvolatile memory. 

The 1756-L1 has a peak backplane current of 0.65 Amps at 5 Volts DC and 0.02 Amps at 24 Volts DC. It also has an average power dissipation of 3.3 Watts and an average thermal dissipation of 11.3 BTU/hour. The storage temperature of the 1756-L1 is from -40 to 85 Degrees Celsius, while its operating temperature ranges from 0 to 60 Degrees Celsius. It also has a noncondensing relative humidity of 5% to 95%. The storage shock of the 1756-L1 is 50 G peak for 11 milliseconds, while its operating shock is 30 G peak for 11 milliseconds. It also has a 10 to 500 Hertz vibration with a maximum peak acceleration of 2.0 G. If the 1756-L1 has a battery in need of replacement, you can only use the 1756-BA1, which is a 0.59g lithium battery. The programming cable compatible with the 1756-L1 are the category 3 serial cables 1756-CP3 and 1747-CP3.

The Allen-Bradley 1756-L1 is a Programmable Automation Controller (PAC) processor module that belongs to the ControlLogix product family. This processor belongs to one of the earlier versions of ControlLogix, the Logix 5550 category.

This module is installed to any ControlLogix chassis such as 1756-A4, 1756-A7, 1756-A10, 1756-A13 and 1756-A17. It occupies single slot of the chassis and module power is provided by the backplane which is energized by a ControlLogix Power supply. 

This controller is capable of controlling medium scale processes. It supports IEC-61131-2 defined programming language standards such as Ladder, Function Block, Sequential Function Chart, Statement List programming languages. 

The integrated RS232 provides interface to programming devices, Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA) and other Visualization and Control systems. It also supports stand-alone and distributed I/O allocation with the use of ControlLogix I/O, Flex I/O and POINT I/O modules.
