CAUTION

For continued protection against risk
of fire, replace the module fuse only
with the same type and rating.

Statutory requirements

EC: Unlicensed operation limits the
radio power. High gain aerials may
only be used to compensate for
cable losses.

Antenna installation

Use Figure 1 as a guide for
installing an antenna and attaching
it to the module.

Wavelengths:
360 MHz = 32.7" (83 cm)

512 MHz = 22.8" (58 cm)
869 MHz = 13.4" (34 cm)

Installation

Choose a power supply option:

•

12–24Vac, 1.5A CSA certified
Class 2

•

15–30Vdc, 1.5A CSA certified
Class 2

•

11–15Vdc, 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 10nF 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.
