Wireless Output Specifications
Dual Input
The 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.
