DSM-WRL
Description: The DSM-WRL is a fully programmable, Native BACnet™ Building Controller, designed to implement temperature monitoring systems without the need for running wires. The DSM-WRL acts as a gateway, translating information from wireless temperature sensors into BACnet analog input (AI) objects that reside in the gateway controller, which can then be accessed by the rest of the BACnet network.
Features:
- Native BACnet firmware
- BACnet MS/TP communications
- No running wires to temperature sensors
- Wireless transmitters measure any resistive input device
- 2500 foot open field range, can be enhanced using repeaters with open field range 4 miles
- Transmitters self-monitor for low battery condition
- 4 button keypad
- Fully programmable in GCL+ to suit custom applications
- Programmable LCD with backlight
- Application Database and Controller Firmware can be flash loaded over the network
- Derived Network Addressing (DNA) for simple integration into a standard network architecture
- Subnetwork can be configured for BACnet MS/TP or expansion I/O
- Built in 10kΩ thermistor
- Real-time clock
- Battery backup
- Service port
Application: The Delta Controls wireless temperature system consists of battery powered transmitter-based temperature sensors that continually monitor ambient temperature, and transmit via a robust 900 MHz spread spectrum RF communications protocol to a wireless receiver. The receiver transfers this information to the DSMWRL, which then updates the AI objects.
The DSM-WRL also features an LCD with keypad that can be used as a stand-alone interface to adjust setpoints. The SubLAN may be configured to support Delta BACstats and other Delta LINKnet I/O devices. The small, lightweight transmitters install quickly and easily using double-sided tape or a screw-mounted wall plate.
Multiple, line-powered intelligent repeaters can be used to extend the range of the RF signal for larger sites. These line-powered repeaters transmit at a higher power for long distance transmitting through buildings and vegetation.
The DSM-WRL’s primary application is monitoring. It should not be used as an input for critical control loops (for example Cooling Tower).
