PROCESS CONTROL   Wireless Bidirectional  with Two Digital Inputs / Outputs
900MHZ TWO-WAY WIRELESS SYSTEMS WITH EXPANDABLE I/O OPTIONS
Besides duplex operation, the bi-directional radio system offers the possibility of lining up additional modules for recording and outputting analog and digital signals. This unique design gives the user flexibility to add on multiple channels of I/O to the pared transceivers in combinations.  Ideal for moving numerous signals within high interference environments without costly cable and conduit runs.
The sets include a receiver, transmitter, and whip antennas with connecting cable. Optional Yagi or Grid antenna
