A-B 1756-L73,namely Allen-Bradley 1756-L73,is one of the ControlLogix series controllers produced by Rockwell Automation.The following is a detailed introduction to the controller:

I.Product Overview

The Allen-Bradley 1756-L73 controller is a standard controller model of the Allen-Bradley ControlLogix product line and is part of the Logix 5570 product category.It is a programmable automation controller(PAC)that can be used to control large applications or process automation applications in factories.

II.Main functions and technical features

Processing capacity:

The controller can handle 100 programs per task at a time and up to 32 tasks at a time.

Equipped with 8MB user memory and 0.98MB I/O memory,it can meet various complex control needs.

Communication capabilities:

Supports a variety of communication options,including ControlNet,Ethernet/IP,DeviceNet,Synchlink:Remote I/O and Data Highway Plus device networks.

It is also compatible with multiple third-party device networks and can be configured to communicate with gateways and protocol converters.

I/O Capability:

It is capable of connecting 128,000 input and output signals and 4,000 analog inputs and outputs.

It can implement local I/O configuration,where the I/O modules are installed in the same chassis where the controller is installed,or distributed I/O topology,where the expansion I/O is installed away from the processor and the I/O is provided through an expansion communication bus.

Configuration and Redundancy:

Supports simplex configuration and high availability(redundant)controller configuration to improve system availability.

Supports controller redundancy and up to 500 controller connections at a time.

Integrated Motion:

Supports motion control on SERCOS interface,analog motion sensors and Ethernet I/P.

Programming and Configuration:

Applicable programming languages​​include relay ladder diagram,structured text,function block diagram and sequential function chart.

Specific programming software(such as RSLogix 5000 or Studio 5000)is required for configuration and programming.

III.Power Supply and Physical Characteristics

Power Supply Requirements:Standard 1756 power supply.

Physical characteristics:

Weighs only about 0.25 kg,with 1 slot width and open housing.

Using USB 2.0,the full rate can reach up to 12 Mbps.

The operating temperature is 060 degrees Celsius and the non-operating temperature is-4085 degrees Celsius.

The operating vibration is 10~500 Hz,which is 2g;the operating shock is 30g and the non-operating shock is 50g.
