Output Circuits, measurement option code 42 (702DX42)
The 702 transmitter has two channels that can each be configured for discrete input or output.
Inputs must be dry contact switch inputs and these were described in a preceding section of this
document. Outputs are a simple switch closure to activate an output circuit. The 702
transmitter output does not provide any voltage or current, the output circuit must have power
of its own. The 702 transmitter output has maximum switch capacity per channel of 26 volts DC
and 100 milliamps. A typical power supply for powering an output circuit can be 24 volts or
lower.
Note
It is very important that the polarity of the output circuit is as shown in the wiring diagrams,
with the positive (+) side of the circuit wired to the CH1+ or CH2 + terminal, and the negative (-)
side of the circuit wired to the CMN terminal. If the output circuit is wired backwards it will
remain active (switch closed) regardless of the state of the output channel.
Note
The output functionality of the 702 transmitter requires that the network is managed by a
version 4 Smart Wireless Gateway, with v4.3 firmware installed.
