CONNECTION WITH GAS SENSORS
Please see the specifics User’s Manuals of the gas sensors.
Please note, that the CE408 has a board with 4 inputs and a board with 4 outputs. In Central
can be installed, a board ES404 and ES414 to have a total of 8 inputs and 9 outputs. The
diagrams, for simplicity, show all the 8 sensors and all relays outputs.
Sensors connection , with three-wire 4÷20mA transmitters, should be performed on the inputs board,
mounted in the base, on the left. The input terminals, “+, - and “S” should be connected to the
corresponding terminals of the sensor.
The connection wire section between the CE408 and the
sensors should be suitable to the distance, as shown in the
table. The connection needs a shielded cable. Shield
should be connected only to the central unit side, and on an
only point of EARTH that has to be equipotential.
The outputs connection, (
Relays
)
should be performed on
the outputs board, mounted in the base, on the right.
The relay output 9 is located on the central
board, see Figure 3 . The nominal load of relay is 250 VAC - 2 A or 30 VDC – 2 A (resistive load).
The relay have changeover free voltage contacts, on the boards, indications
NA means NO
(
Normally
Open
),
NC
(
Normally Closed
),
C
(
Common
), refer to the relays in the normal position (not powered). If an
output is configured as POSITIVE LOGIC , the NO contact will become NC and NC will become NA.
