    SiOne can be humidity, temperature, barometric pressure, differentia pressure, carbon dioxide (CO2), volatile organic compounds (VOC), particulate matter (PM) and/or Analog signal transmitters (it depends on model). The SiOne line combined with an internal and/or external sensors provide state-of-the-art functionality. Various models are available including wall, duct or remote sensors. SiOne is introducing powerful programming capabilities. Settings of the device can be modified through USB programming unit, PC software or Modbus interface. Modbus RTU baud rate, Modbus RTU address and type of Analog outputs can be fast changed by configuration jumpers.

    Schemat połączenia SiOne


    ( 1 ) – RS-485 interface (Modbus RTU) or Industrial Ethernet (Modbus TCP)
    ( 2 ) – programmable relay output On/Off (option)
    ( 3 ) – programmable (up to 3) Analog outputs: 0…5 V, 0…10 V, 0…20 mA or 4…20 mA (option)


    SiOne transmitters offers Fieldbus (RS-485 – Modbus RTU) or Industrial Ethernet (Modbus TCP) interfaces. The SiOne line can provide up to three fully programmable and scalable Analog outputs (types of output: 0…5 V, 0…10 V, 0…20 mA or 4…20 mA). Analog output can be modified by configurations jumpers, Modbus interface or USB programming unit. SiOne transmitter with relay output can be used as simple binary sensor (pressostat, hygrostat, thermostat, CO2-stat, …). Threshold and hysteresis of output can be also modified by Modbus or programming unit.
