Product Description
The Delta Field Modules are small expansion I/O boards
that provide remotely expandable I/O to Delta’s BACnet
Controllers. The DFM-400P Pulse Input Field Module
provides four pulsed inputs and communicates directly on
a BACnet RS-485 MS/TP network where it functions as an
independent BACnet device and the pulse counter values
and PI objects are accessible over the MS/TP network.
Ideal for electrical, water, gas, and various flow meters,
the DFM-400P has four pulse inputs. Two inputs support
pulses from 0 to 200 Hz and the other two inputs support
pulses from 0 to 2000 Hz.
Any additional strategies associated with the pulse
counter values are typically programmed in GCL in other
controllers on the network.
