6 Installation
6.3.2 Electrical connection
Before powering on the S551, please connect all sensors with the S551.
•
For SDI sensors, connect them to the S551 through connectors 1
and 2 on the case.
•
For Modbus sensors, connect them to the S551 through
connectors M on the case.
•
For analog signal sensors such as 0 ... 20 mA, 4 ... 20 mA, 0 ... 1
V, 0 ... 10 V and pulse signal sensors, you can connect them to the
S551 through connectors 3 and 4 according to the pin assignment
shown in section
on page 11.
Remarks:
•
The S551 can automatically detect the SDI and Modbus sensors
from SUTO, which include flow sensors, dew point sensors, and
extension modules (such as power meters, ultrasonic flow meters,
and analog extension modules).
•
The S551 cannot automatically detect the process signal sensors.
You must manually add the appropriate sensor types to the S551
by using the S551 configuration menu. For more information , see
section
7 Configuration
The S551 provides factory settings according to orders. All settings are
stored in the S551. To change the factory settings on site, see section
