X7121 Wireless Pulse Counter Bridge

X7121 Wireless Pulse Counter Bridge

The X7121 Wireless Pulse Counter Bridge transmits pulse counter, digital and analogue data over a range of 1-3 Km through buildings and 10Km line of sight. All parameters can be displayed in scaled units on both the transmitter and receiver. Multiple TX7121 Transmitters can be mapped to a single RX8100 Base Station.

Description:

The X7121 Wireless Pulse Counter Bridge transmits pulse counter, analogue and digital data by means of low power VHF or UHF radio. An LCD display is provided so that the pulse counter total, digital inputs, and scaled analogue input can be continually displayed in real time at the both the transmitter and receiver. Dots will appear on the LCD display to indicate a radio transmission. The display is also used for the set up menu. The RX7121 has a programmable Link Fail relay which will de-energize if communication with the TX7121 is lost.

Multiple TX7121 transmitters can be used to transmit data to a single RX8100 XNET Receiver. The destination of each input is programmed into a TX7121 by rotary DIP Switches along with a transmission time. The TX7120 transmits the total number of pulse, the status of the analogue and digital inputs at a programmed time interval to the outputs on the RX8100 Receiver. The receiver data can be presented as physical outputs or in serial form direct to a SCADA package.

The TX7121 low power, battery operated variant will transmit the status of the inputs at preset times or when any change occurs in the digital and analogue inputs or when the pulse counter has counted 255 since its last transmission. In addition, a battery status indication is displayed and transmitted to a digital output on the receiver.
