SiOne transmitter is used to measure climate parameters, such as: temperature, relative humidity, atmospheric pressure, pressure difference, carbon dioxide (CO2) concentration and / or analog signal 0 ... 10V / 0 (4) ... 20mA (depends on the model) . A simplified diagram and a table with the description of the terminal and elements of the SiOne transmitter are presented below. To power the device, use a power supply with an output voltage compatible with the converter specification. The power supply is connected using a screw or spring terminal (located under the device housing cover) or a DC-JACK connector (for the Ethernet version). The basic parameters of the SiOne transmitter are configured by configuration jumpers (marked as DIP SW).
Signal and electrical connection
TB: V - power supply11,5…27 VDC
TB: GND - GND (digital and analog)
TB: A, B - RS-485 interface
TB: 1 - analog output no. 1 (for versions Si-… A1, Si-… A2, Si-… A3) / relay output 1 NC (O) (for versions Si-… P1)
TB: 2 - analog output no. 2 (for Si-… A2, Si-… A3 versions) / relay output 1 COM (for Si-… P1 versions)
TB: 3 - analog output no. 3 (for Si-… A3 version) / relay output NO (C) (for Si-… P1 version)
Red LED - power supply indicator
Green LED - data transmission indicator
The exact size and location of the sensor depends on device version
DIP Switch configuration jumpers (MODBUS address, RS485 baud rate, analog output type)
Each SiOne transmitter has two LEDs that indicate the device's operating status. LED function description:
Red LED (L1)
ON when the transducer power supply is connected (continuous light)
Green LED (L2)
ON when data is being transmitted (blinking light)
The basic parameters of the device are configured with the use of configuration jumpers (marked as DIP SW). Configuration of the baud rate and MODBUS RTU address should be performed only with disconnected power supply. The new settings will be active as soon as the device is connected to the power supply. If you change the settings while the power is on, the new settings will take effect after restarting the device. DIP Switches replaced the configuration jumpers that were available in older versions of the device. The settings in the old and new version of the transducer are the same (OFF = jumper off / ON = jumper on).
MODBUS RTU address - configured with jumpers1…5
The address is calculated according to the following formula:
MODBUS RTU baud rate - configured with jumpers 6…7
9600 bps : Z6 = 0, Z7 = 0
Analog output standard configured with jumpers 8…10
via Modbus : Z8 = 0, Z9 = 0, Z10 = 0
Be careful when connecting the device. Incorrect connection may damage the device and/or damage other devices that are connected to the device or system.
All connections must be made when the power is off!
