About the D4-440DC-1

D4-440DC-1 is a central processing unit (CPU) module developed by Automation Direct. A member of the DirectLogic 405 series, this module can interface with all programmable logic controllers in the same series. No memory is built into the system, but separately purchased memory cards are available, such as D4-UV1 or D4-EE-2. The D4-440DC-1 is a DC-powered module with an input range of 20 to 28 VDC.

Built for fast boolean execution and optimal communication, D4-440DC-1 provides a user-friendly experience. Two communications ports are built into the module for programming and network connectivity. The first port exclusively provides a port for programming the module. A 15-pin input, Port 1 supports RS232 inputs with a 9600 baud. A variety of programming devices, including personal computers, handheld programmers, and other operator interfaces, are supported using this port. Port 2, conversely, is a slave-only input. A 25-pin auxiliary port, this connection supports RS232/422 inputs with user-selectable baud rates. CPU dipswitches allow the user to select the baud rate of the second port. The front of the module features a CPU key switch, allowing selections between RUN, TERM, and STOP. Six CPU status indicators are also found on the front plate. These indicators alert users to successful or unsuccessful PWR, RUN, CPU, BATT, I/O, and COM connections.

Be sure to follow all manufacturer-provided installation and storage parameters. All wiring and installation instructions and diagrams are easily accessible in the series manual and device datasheet.

Reviews For D4-440DC-1

Internal Review
(4.0)

While some DL405 modules can be used as stand-alone units, the D4-440DC-1 module must be used with other modules such as a base, I/O configuration, and I/O modules. Not only does this module have to be used with other DL405 units, but it must also be programmed. - AX Control Tech
