The 1785-LT2 PLC-5 processor designed by Allen-Bradley/Rockwell Automation is a classic programmable controller for high-performance and industrial use. The PLC-5 processors are integrated into bigger systems which are intended for controlling machinery. The various features of these controllers are used for providing the detailed set-up of the controller. This model of controller has a maximum of 13k words of user memory or a SRAM of 13 Kilowords with an option of expanding to 17k or 21k, depending on user needs. The 1785-LT2 processor features two channels, one DH+ channel and one remote I/O channel. Also, the controller has 1024 total maximum I/O and 1024 total  analog I/O. Every rack of the controller has an I/O scan time of 10 milliseconds at 57.6 kilobits per second, 7 milliseconds at 115.2 kilobits per second, and 3 milliseconds at 230.4 kilobits per second. Other specifications include a total number of 93 chassis for the maximum I/O chassis, no I/O Extended Local Chassis, and 32 maximum Universal Remote I/O Chassis per I/O link. Besides that, the controller has one (1) RS-232-C/422-A/423-A port and an expansion port for control coprocessor.

The temperature levels of the working environment for the 1785-LT2 include a temperature range of 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and a storage or non-operating temperature range of -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit). Usually, this controller is used in a hazardous environment where there is a danger of explosions. Also, the 1785-LT2 controller/processor often operates in an environment where there is a level of pollution rated for Category II applications at the industrial level. The controller can also be used at an altitude of up to 2000 meters (6561 feet) without derating. The users should be careful when using a device like this in hazardous environments, because there is a possibility that an electrical arc will occur if the cable and the terminal block are connected or disconnected when the power is on.
