RF Wireless DIN System

The A75x series offers simplicity and reliability in a point to point, multipoint or wireless mesh system. One A753 transmitter can communicate with multiple A750 receivers for redundancy. A repeater can be added simply by placing in between a transmitter and receiver, no programming is required. Three radio options are available: long range 900MHz 1W, 900MHz 50mW and 2.4GHz 63mW. In addition to transmission of the industry standard 4-20mA, our transmitters can directly process thermocouples, RTD and switch states. Up to 32 inputs may be transmitted with one transmitter when the A753 is paired with our A16000 expansion module.

DIN Rail Wireless DC Powered 4-20mA	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 temperature input using a 2 or 3 wire RTD or thermocouple and two digital inputs. 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. The 900MHz version is also available with a low cost 50mW output. Optionally the 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.
DIN Rail Wireless DC Powered RS232/RS485 Modbus RTUA	The A750-Mod transmits/receives RS232 or RS485 data 2-wire or 4 wire and can operate in Modbus RTU mode as a master or slave. The A750-Mod is available in three versions: 900MHz 1W, 900MHz 50mW, and 2.4GHz 63mW operating voltage is +24VDC (+11 to 32VDC).
DIN Rail Wireless DC Powered Pulse Transmission	The A753-PL transmitter and A750-PL receiver are designed to transmit a pulse of up to15Hz (inclusively) wirelessly. The pulses are recreated at the receiver as a 0 to 5V output pulse. The operating voltage for both the transmitter and receiver require +24VDC (+11 to 32VDC). These instruments are designed for short range transmission with line of sight, contact the factory for details.
