D4-450DC-1 is a central processing unit (CPU) module developed by Automation Direct, Facts Engineering, and Koyo. A member of the DirectLogic 405 family, it is capable of interfacing with programmable logic controllers from the same series. A built-in flash memory of 7.5K is available on the device, but additional memory space is available. Operating on DC power, the supply needed to power the module measures at 24 VDC.
A premium CPU module, D4-450DC-1 features a number of communications abilities. Four separate communication ports are featured on the module. Port 0 is a programming port featuring a 15 pin connector. This port can support RS232 inputs with a 9600 baud rate. Port 1 is a general purpose, 25 pin connector port capable of supporting RS232/422 inputs. Baud rates for Port 1 are user selectable using the programming software. Port 2 is a phone jack used for programming purposes. This RS232 input has a selectable baud rate of up to 38.4Kb. The final port is another general purpose port, capable of inputting RS232/422/485 connections. Like Port 2, baud rates for Port 3 are user selectable with the proper software. CPU scans from the module can be altered, depending on user need. Three scanning systems are featured on the device. These include variable, limited, and fixed scan rates. Six CPU status indicators and a CPU keyswitch complete the front plate of the module.
Some device damages are preventable by following all provided installation and storage parameters. A complete guide to wiring and installing the module can be found in the user manual and device datasheet. The original manufacturers, Automation Direct and Koyo, provided the original technical support for D4-450DC-1.
