DFM-200
Description: The DFM-200/202/220 provide remote I/O to Delta’s BACnet™ Controllers. These field modules provide two 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-200 model only).
When connected to a LINKnet network the DFM-200/202/220 provides remote input and programmable output capabilities to the controller. When connected on the MS/TP network (DFM-200 only) the modules function as independent BACnet devices with inputs accessible over the BACnet MS/TP network.
Features:
- Native BACnet device (DFM-200 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
Application: The DFM-200/202/220 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.
Accessories:
- RPT-768—Delta Network Repeater for BACnet MS/TP
- TRM-768—Delta Network Terminator for BACnet MS/TP
