NAS DTMF Controller

The NAS  DTMF Controller provides cost effective  remote monitoring and control.

Using 2-way, wireless DTMF tone telemetry, this product provides an economical solution for controlling and monitoring your facilities without the costly build out of infrastructure to access the location. Equipped with a 5 watt UHF/VHF radio transceiver operating on your licensed frequency provides security and range not available with products that operate in the unlicensed band. With range up to 15 miles from fixed base sites the product can be controlled from the ground with a standard 2 way portable radio or configured with a fixed base control facility to operate multiple sites. 

The unit comes equipped with customer configured “voice annunciation features” allowing receipt of over the air command confirmation on your 2 way radio or base equipment. Equip the base with a TELCO line interface unit and control and monitor your facilities by using the touch pad on your telephone. 

With 4 Optical Isolated Inputs and 2 independent Relay Controlled Outputs the DTMF Controller provides the capability to monitor and control numerous devices at your facility. Programmable time out features allow automatic output reset. Designed with flexibility and simplicity in mind the unit can be configured in minutes with a a simple terminal program operating on your PC. 

Equipped standard with our low profile chassis the device will fit anywhere you can find space and can operate on either AC or DC power. The onboard DC-DC Converter provides complete battery isolation for isolated ground battery plants. Have a custom application, that is not a problem for the staff at North American Signal, we will find a way to adapt the equipment to meet your requirements.
