DFC-304-R3
Description: The DFC-304R3-240 is a fully programmable, Native BACnet™ Advanced Application Controller that communicates on an RS-485 LAN using the BACnet MS/TP protocol. Direct 240 VAC line voltage terminal connections are provided for 1, 2 or 3 speed fans. Room temperature can be a standard 10KΩ sensor or BACstat II, connected via a secondary LINKnet network and a 24 VAC power out connection.
Features:
- Native BACnet firmware
- BACnet MS/TP communications
- Stand alone operation or on BACnet
- Fully programmable in GCL+
- Pre-loaded fan coil application database
- Direct connection to BACstat II (DNS-24 or DNS-24L)
- Direct connection for up to 2 tri-state valve Actuator
- 3 relays rated for motor loads to control 1-, 2- or 3-speed fans, complete with interlocks and time delays for equipment protection
- Slim design fits into narrow fan coil units
- Power supplied by power mains (on-board 24 VAC transformer included)
- Derived Network Addressing (DNA) for simple integration into a standard network architecture
- Service port
Application: The DFC-304R3-240 is designed for fan coil control.The binary model, with 4 additional triac outputs for heating and cooling, covers a wide range of fan coil unit applications, including two- and four-pipe fan coils.
The DFC-304R3-240 allows for sequence modifications as required by the design engineer or building owner. It provides simple, easy-to-install fan coil control solutions for office buildings, hotels or residential buildings.
