With single or dual channel capacity, the Rosemount™ 702 Wireless Discrete Dual Input or Output Transmitter is a cost-effective, reliable wireless solution. This transmitter offers control system access to discrete points that are otherwise not connected due to wiring costs and lack of I/O, and takes input from a variety of non-powered switch types such as pressure, flow and level switches. Easy to install, this device can be used for simple control when outputs are being used or as a simple switch.
