Analog input 0-10V
Analog input 0-10V is described as
INPUT 0-10V
. To this input one can attach any source of signal within the measuring
range 0-10V, e.g. CO concentration meter
2
.
The connection is done using two wires:
•
U
- signal input,
•
GND
- ground.

type FUJI ZFP9. Another type of meters are
connected in the same manner. After meter connection to the analog input 0-10V one should adequately configure the
regulator so that it could read data from the meter. One should indicate the place of connection of the meter and the type
of meter – additionally, individual calibration can be made of the particular meter.

Inputs of S300 measurement sensors
LB-762 regulator is equipped with two inputs permitting attachment of any S300 sensors, extending measurement possibilities
of the regulator. In typical cases these are concentration meters CO
2
LB-850 or hytherographs LB-710.
For connecting sensors the following connectors are used:
•
S300 #1
- sensor input no. 1,
•
S300 #2
- sensor input no. 2.
The connection is done using two wires that they provide power supply to the meter and are used for data transmission:
•
”+”
- power supply,
•
GND
- ground.
S300 interface is a current loop which permits any polarization of the attached sensor, thus the manner of connection
(sequence of wires) does not have any importance here.

concentration meter type LAB-EL LB-850
presents a scheme of connection of concentration meter CO
2
type LAB-EL LB-850. The meter can be attached
to any of the two S300 inputs which LB-762 regulator is equipped with. After connection of the meter to S300 input it is
necessary to properly configure the regulator, so as to ensure that it could use measurement data from the S300 input.
