The D100CA40H is a programmable logic controller, manufactured by the Cutler-Hammer brand. It is powered by 115 Volts of DC input voltage and it has a 24 Volt AC input and triac output; this module functions on 40 I/O capabilities. The D100CA40H has a high-speed counter and is equipped with analog capabilities. The maximum counting speed of this part can reach 4 kHz. It can be expanded from 40 I/O to 80 I/O, or from 24 inputs and 16 outputs up to 48 inputs and 32 output units. The D100CA40H has a standard weight of 0.454 kilograms. It can be combined with 8 I/O and 20 I/O in order to meet the requirements for a system functioning on the industrial level. The D100CA40H can be easily installed using cable wires. The Programmable Logic Controller (PLC) and expander can be directly connected, using the same cable wires. Users should note that if using an analog module with the D100CA40H and a controller, the later should have a direct connection with the system or computer.

Also, note that the analog module will not affect the I/O count of the D100CA40H. The D100CA40H has the built-in feature of a PROM writer which is used to record and store programs. It is especially used for industrial work. The D100CA40H is helpful in retrieving lost information. It can help use the same information for working with applications or machine tools which can perform the same functions. The D100CA40H can also be used to send information or data for updating or changing the functioning of a system.
