3.3.3: Wiring the Input Switches
(Optional)
To properly wire a switch input device to the Dual Analog Input Transmit-
ter simply follow the wiring diagram provided below. Please note that
loop power does NOT need to be supplied as the Transmitter supplies the
monitoring power. The Dual Analog Input Transmitter has the capability
of monitoring two input switches.
The most common application for the switch inputs is to monitor a contact
closure. However, the input switches must only be attached to simple de-
vices. A simple device is one that meets the conditions set forth in the In-
trinsic Safety Control Drawing, which can be found in the Technical
Specifications section of this manual.
The diagram shown in Figure 3.8, below, refers to the circuit board found
at the base of the Transmitter, within the junction box. Before connecting
wires to the terminal blocks, the input wires should be routed into the back
of the enclosure and threaded through center of the circuit board.
Wiring the Dual Analog Input Transmitter to a
non-simple device (such as an explosion proof
device)
voids the intrinsic safety
of the Transmit-
ter. A simple device is one that meets the condi-
tions set forth in the Intrinsic Safety Control
Drawing found in the Technical Specifications
section of this manual.

Note that the Transmitter may continue to monitor the analog input loops
in addition to the contact closure monitoring. Also, the contact closure
monitoring requires NO POWER to be supplied to the loop, nor does the
user have to enable or enter any information via the NEXT and ENTER
buttons, as this is done automatically by the Transmitter.
No messages indicating the status of a monitored contact closure are dis-
played on the Transmitter LCD. The status of the input switches can be
found in the Wireless Management Toolkit under the Transmitter View.
An open contact closure is indicated as an ‘O’ and a closed contact closure
is indicated as a ‘C’ on the Transmitter View (see Wireless Instrumenta-
tion Management Toolkit Manual section 8.1) for each input switch.
