Installation
Choose a power supply option:
•
12–24Vac, 1.5A CSA certified
Class 2
•
15–30Vdc, 1.5A CSA certified
Class 2
•
11–15Vdc, 1.5A
•
Solar panel with battery
After choosing a power supply
option, wire the module as
shown in Figure 2.
ote:N All I/O must be SELV.
a
Digital outputs are relay contacts. For ratings
see your product user manual. For AC supply,
use 10nF 250V surge capacitor.
For DC supply, use bypass diode.
b
Analog outputs are either loop powered or
externally powered. Output loops are earthed
(not floating).
When the wiring is completed,
connect the module to a
computer (PC) and configure
it using the configuration
software. For details, refer to
the user manual.
Before operating the module,
read the sections on operation
and configuration in the user
manual to take advantage of all
product features.
WARNING
