Wireless Communication System

Aysix Technologies offers reliable wireless solutions for sending and receiving process information up to 20 miles.  Providing solutions for everyday applications or within explosion proof areas, point to point, or multi point with frequency hopping, self healing, 900mhz for long distances, and 2.5Ghz for shorter range is all within our scope .   We have solutions that are quicker to implement that wire, may be more cost effective than running wire, and can even help in areas without power.   Questions about your particular application?  We can provide you with a proven solution, with an onsite demonstration for peace of mind.  Just contact your local representative.


Combining simplicity and functionality in an industrial point to point RF transceiver, the A750 receiver and A753 transmitter offer quick installation and reliable transmission of a 4-20mA or thermocouple signal and two digital inputs and outputs. RF channels are dip switch selectable, no computer is required for setup. Both the transmitter and receiver operate on +24VDC (+11 to 32VDC). 1 Watt of RF power ensures excellent distance and reliability in the harshest of environments. In RSSI mode the RF signal strength can be monitored. Operating at 900 MHz with industry proven frequency hopping spread spectrum maintains signal integrity and provides excellent transmission distance. A low power 2.4GHz, 63mW DSSS (direct sequence spread spectrum ) version is available. Receiver includes two relays with normally open and normally closed contacts. Contacts are rated for 0.5A at 125Vac or 2A at 30 VDC. A third relay is used as an alarm while monitoring RF signal strength. If signal strength becomes inadequate alarm will activate. Both the transmitter and receiver are expandable utilizing AnaBus and the A0000 expansion modules. The modules allow expansion of both analog and digital I/O at the transmitter and receiver.


Requirements for wireless are generally not critical for smaller distance, and applications that have multiple wireless points that will self heal. This means that if for some reason communication between two points is broken, the device will search for anther device to communicate with, and pass along to the end receiver.   For long distances, line of sight is required.   A repeater can be used to achieve this.  This usually involves mounting the transmitting antennae, or repeater in a tower, or a high location that permits a clear line of sight to the receiver. Your distributor has a test kit and can go to your site to prove out your actual application.
