Description
The TXA15101E is an analog and digital 151 MHz transmitter. The analog signal, normally 4-20mA is transmitted and then
recreated at the receivers (RXA15101E) analog output. Also, the normally open digital contact can be simultaneously
transmitted with the analog signal. This eliminates the high cost of wiring and has the flexibility of wireless data collection.
Using 151MHz has superior penetration in congested industrial environments with steel construction. Higher frequencies such
as 433MHz or 915MHz tend to reflect of metal and make wireless data collection difficult.
The on board 12-way dip switch sets the ID for the transmitter. This has to be matched to the 12 way dip switch on the
receiver for a
No case version is also available - TXA15101
The TXA15101 transmitter is the PCB assembly only, while the TAX15101E transmitter is enclosed in an alloy metal case.
External supply connection and SO239 antenna socket is provided with the transmitter.
Modes
The one way mode switch on the board selects the sampling transmission rate.
Mode Sw. 1 OFF : Sample Rate 2 to 62 seconds.
Transmitter will transmit a 1.5 second transmission burst and then stop for the time selected. The time is user selectable
between 2 to 62 seconds by adjusting the trimpot of the transmitter board. If the digital input is activated during the "off delay"
period the new data will be transmitted immediately. The transmitter will indefinitely transmit if the supply is connected.
Mode Sw. 1 ON : Off Delay 1 to 10 minutes.
Same as mode 1 except the sample rate is user selectable between 1 to 10 minutes.
Longer sample rates are possible. Contact Elsema.
