Quick Start Guide
Integra Series 37
For a 4-wire function, the input(s) is connected to an input channel and its corre-
sponding sense channel. Input channels 1 through 10 are paired to channels 11
through 20. When an input channel is closed, its paired channel and the back-
plane isolation relays (channels 24 and 25) also close.
For example, closing channel 1 also closes channels 11, 24, and 25.
