A-B 1756-L73 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.

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.
