With SATEL radio modems, setting

up a local data transfer network is

quick and cost effective. Your wireless

network is independent and free of

operator services. The cost of opera-

tion is either free of charge or fixed,

depending on the frequency used.

SATELLINE radio modems are type-

approved in over 50 countries. For

the latest information, please visit our

website www.satel.com.

SATELLINE radio modems are always

on line, and provide reliable, real-

time data communications over dis-

tances ranging from tens or hundreds

of metres up to around 80 kilome-

tres. Thanks to a store and forward

function, any radio modem in a net-

work can be used as a master station,

substation and / or repeater.

SATELLINE radio modem networks

are flexible, easy to expand and can

cover a wide variety of solutions from

simple point-to-point connections to

large networks comprising hundreds

of modems. Even for expanded net-

works, only one operating frequency

is required.

With over 20 years of experience,

SATEL Oy has grown into one of the

leading radio modem manufacturers

in the world. As a result of our per-

sistent and innovative work in both

product design and international

marketing, we now offer an extreme-

ly large selection of radio modems,

and operate through an extensive

and skilled distributor network all

over the world.

i-LINK

Pulse counter and I/O-converter

Wireless World – Local Solution

SATEL i-LINK is a compact and cost-effective member of the SATELLINK

product group of I/O-converters. Together with the SATELLINE-1870,

-1870E or -1915 radio modem it provides a handy tool for setting up

wireless control and surveillance applications based on pulse counting and

transfer of digital I/O-information.

The i-LINK is equipped with a pulse counter input and two digital inputs and

outputs. It is connected directly to the SATELLINE-1870, -1870E or 1915

radio modem through an RS-232 serial interface. The i-LINK is designed for

easy and cost-effective transfer of information for multitude applications in

our every-day life. Numerous applications exist in the domains of industrial

production, public utilities (water and energy supply systems) as well as in

household use (security applications, business).

In order to offer even more flexibility, Modbus compatible version is avail-

able too.

Distributor:

The i-LINK is a versatile converter, equipped with a pulse coun-

ter input and two digital inputs and outputs. It is connected di-

rectly to the SATELLINE-1870, -1870E or -1915 radio modem

through an RS-232 serial interface. The pulse counter is used

for on-line control of e.g. water, electricity and gas consumption,

while the I/O-converter is used for transfer of contact informa-

tion and readings of field instruments like gauges. The i-LINK

is designed to receive pulse information in the Multipoint mode

only, whereas I/O digital status information can be transferred

in both Multipoint- and Point-to-Point systems. In a Multipoint

application, various information from a number of sub-stations

is gathered to the master station. In the Point-to-Point mode any

change of status in a digital input triggers a transmission in a

few milliseconds.

The i-LINK has two relay outputs. The combination of a pulse

counter and digital I/O-converter makes the system flexible and

versatile. Digital I/O ports can be used for driving motors and

controls, at the same time that the pulse input port is used for

metering other information.

Depending on the topology of the area wireless working dis-

tances can vary from tens of metres up to a few kilometres.

Technical specifications SATEL i-LINK

Pulse counter and I/O-converter for wireless applications

Remote reading of energy and water

meters of households and office proper-

ties in a densely inhabited urban area is

another feasible and labour-saving ap-

plication.

The readings of the electric meters are

connected to the digital input of the

i-LINK, converted to engineering units,

transmitted to the aerial control station

through the SATELLINE radio modem and

finally stored by the master computer.

At a farm, the i-LINK can be used for

automation of the control of irrigation

machines. The devices are switched on

individually, based on the reading of a

temperature or light sensor.
