About the D4-FILL
The Automation Direct Facts Engineering Koyo D4-FILL is a filler module. This unit was developed for the DirectLogic 405 series of programmable logic controllers. From the series, modules with 4, 6, and 8 slots are available, though these connection points are not always used. Modules like this are used when there are open and unused slots on the operating logic controller.
As a filler module, D4-FILL does not have any integrated system capabilities. It does not offer any I/O interfacing and cannot communicate with the logic controller or its installed central processing unit (CPU). This module is designed to fit into any open I/O slot on the controller. It protects these unused slots from any damages. By using D4-FILL, these empty slots are protected from outside environmental damages. These damages include floating particles such as dust, debris, or accidental contaminants.
Installation of the filler module is the same as installing any other module into the I/O slot. D4-FILL is simply placed into the empty slot on the logic controller and protects it as a working module would. Though the device does not have any integrated system, temperatures should be monitored to protect the controller it is installed in. Logic controllers from the DirectLogic series can withstand ambient temperatures no lower than 0℃, or 32℉, and no higher than 60℃, or 140℉. Installation of the filler is simple, but detailed diagrams and usage parameters are available in the series manual and the device datasheet. Automation Direct and Koyo provided original technical support for all DirectLogic 405 series members.
