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.
