RRTU-AP
Remote
Terminal Units (RTU)
These are
small units with
several inputs and
outputs, installed
in the field at a
distance of a few km
from the controller.
The unit is
connected locally to
the elements
(solenoids, meters,
sensors etc.), it is
constantly in
communication with
the controller
receiving
operational command
and transferring
data back to the
controller.

There are 3 types of
RTU:
The system consists
of a CRTU adapter inserted
into the controller, a 3
wire single cable that can
be up to 6 km long along
which the CRTU units are
installed.
A combination of units with
a total of up to 128 outputs
can be installed along the
cable. Two such cables can
be installed on one
controller.
Radio RTU AP (1 way
RRTU)
This system
transmits a radio signal
from the controller to a
distance of up to 5 km
(depending on the field
conditions), the signal is
received by the radio RTU
and can open or close
outputs. (This unit does not
include inputs).
The system consists of:
-
Serial Transmitter (SRT):
includes: 1W-RRTU
adapter (located inside
the controller), data
cable, radio transceiver
and an antenna.
-
Field
Units: includes:
-
2 or
4 12 VDC latching
outputs
-
A
lithium battery, 3.6 VDC
which lasts under field
conditions up to 2-3
years.
-
The
unit is enclosed in 100%
water proof, epoxy
molded housing.
-
Each
unit is loaded with its
own "private" code
number using a portable
terminal.

There are two basic
CRTU models
Cable RTU (CRTU)
The system consists
of a CRTU adapter inserted
into the controller, a 3
wire single cable that can
be up to 6 km long along
which the CRTU units are
installed. A combination of
units with a total of up to
128 outputs can be installed
along the cable. Two such
cables can be installed on
one controller.
-
CRTU-2: 2 Outputs - 12
VDC latching; 4 Inputs
(On/Off)
-
CRTU-4: 4 Outputs - 12
VDC latching, 8 Inputs
(On/Off),
4 Analogs - 4-20 mA or
0-10 V
