Wireless output specifications

Dual input
The Rosemount 702 Transmitter will accept the input from one or two single pole single throw switches
on inputs S1 and S2. The wireless output of the transmitter will be both a primary variable (PV) and a
secondary variable (SV). The PV is determined by the S1 input. The SV is determined by the S2 input. A
closed switch drives a TRUE output. An open switch drives a FALSE output.
