Banner Engineering’s SureCross DX70 delivers two-way RX/TX communication with acknowledgement at up to 4.8km (3mi) along line-of-sight. Four discrete and two analogue inputs and outputs are available.

If the radio frequency signal link is lost, the network can direct outputs to a predetermined state. There is also a built-in signal strength indicator. Models in North America use 900 MHz; those in Europe, Asia and Brazil use 2.4 GHz.

The unit has been desiged for industrial environments.
