Application
The SiOne programmable transmitter can be used for climate control by measuring these air parameters: temperature, humidity,
air pressure, differential air pressure and/or carbon dioxide CO2 (depending on the model). Basic parameters of the device can
be configured by using configuration jumpers. The user can program the SiOne transmitter (change standard analog outputs,
scale analog outputs, check measuring parameters, …) by using the programming unit ((CODAP-RS485) and service PC software
(APConfigPC [SiOne]).
Figure 1. SiOne in simple application
Each SiOne transmitter provide RS-485 interface (MODBUS RTU protocol) that is used to connect the device with PLC, HMI or
PC. Some SiOne transmitters (Si-…A1, Si-…A2 and Si-…A3 versions) provide one, two or a maximum of three analog outputs (0..5
V, 0…10 V, 0…20 mA or 4…20 mA - programmable; 12-bits resolutions of DAC).
