1756-L84E

The Allen-Bradley 1756-L84E is a ControlLogix controller. This controller belongs to the high-end controller with modern design and connectivity. This controller is ideally used for large applications as it can be used to interface and control Input and output devices, specifically, 128,000 Discrete Input and Outputs and 4000 Analog Inputs and Outputs.

It supports local I/O control as well as implementation of distributed I/O architecture utilizing one or more communication protocols such as EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink, and Third-party process and device networks

The 1756-L84E comes with integrated communication port such as One (1) Ethernet I/P. This embedded port supports 10/100/1000 Mbps transmission speed and may be used to communicate with Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA) and other controllers through messaging instructions within the same Ethernet network. The USB port is a USB 2.0 that supports 12 Mbps communication speed.

The 1756-L84E has a built-in user memory amounting to 20MB. An expansion non-volatile memory may be installed with the use of 1784-SD2 which is a 2GB Secure Digital (SD) card. This controller does not require a battery to retain the contents of the volatile memory as it comes with the modern energy storage solution, eliminating the need for use of batteries, making the controller user and environmentally friendly.

The 1756-L84E ControlLogix 5580 Controller by Allen-Bradley is a high-performance controller with up to 128,000 I/O which enhance machine automation and increase performance. It comes with 20MB of user program storage memory and allows for expanded and long-term program storage via the optional pre-installed 2 GB Secure Digital Card (1784-SD2). Embedded on the controller is an energy storage module which removes the need for an extra battery and the entire controller draws a backplane current of 5mA at 1.2V DC and of 1.2mA at 5.1V DC. The 1756-L84E has an operational thermal dissipation of 21.2 BTU/hr, and provides 50V isolation between USB port-to-backplane, Ethernet port-to-backplane, and USB port-to-Ethernet port, utilizing basic insulation tested at 1000V AC for 1 minute. The controller fits into any 1756 Chassis slot and uses a single slot width. The number of tasks performed by the controller is unlimited through the local I/O event triggers mechanism and programming are achieved using the Studio 5000 Logix Designer Application Version 3.0 or greater. It also has a built-in embedded 1 GB Ethernet port which supports a maximum of 250 nodes and provides enhanced performance, wider communication, and integrated motion control on the EtherNet/IP network. The controller is designated the T4 temperature code and is IEC tested to operates at 0-60 deg. Celcius temperature range, and functions without de-rating at 5-95% non-condensing relative humidity limits. The 1756-L84E can withstand a shock of 30G and a vibration of 2G and the entire controller weighs approximately 0.394kg.
