DFM-400 / DFM-404 / DFM-440
The DFM-400/404/440 provide remotely expandable I/O to Delta’s BACnet™ Controllers. These field modules provide 4 universal inputs, in three different output configurations, and are capable of communicating on Delta’s LINKnet network or directly on an RS-485 BACnet MS/TP network (DFM-400 model only).
When connected to a LINKnet network the DFM-400/404/440 provides remote input and programmable output capabilities to the controller. When connected on the MS/TP network (DFM-400 only) the modules function as independent BACnet devices with inputs accessible over the BACnet MS/TP network.
Application
The DFM-400/404/440 suits a diverse range of application needs where additional inputs and outputs are required, or where a small number of I/O’s are remotely located.
Features
- Native BACnet device (DFM-400 only) supporting communication on an RS-485 BACnet MS/TP network
- Supports communicating on LINKnet
- Easy-to-mount housing
- Derived Network Addressing (DNA) for simple integration into a standard network architecture
- Extended temperature range for extreme ambient situations
