Environment Variable Data Acquisition Module
Product profile and purpose
SZNY-1000 data acquisition module uses GPRS protocol to make communication, and transmits the 3-channel temperature acquisition signal and dual-channel on-off sampling signal to the central station, and makes relay control via dual-channel on-off output. The module has the functions of perpetual calendar, and secondary development of software interface protocol.

Main characteristics
● It is equipped with 3-channel PT1000, 2-channel on-off input, and 2-channel on-off output.
● Some external output protocols support making modification according to agreed protocol.
● All circuit parts are equipped with three proofings (moisture proofing, salt spray proofing and fungus proofing), to adapt to outdoor sunshine and rain.
● It reserves one-channel 485 port (modbus supports master/slave mode, and subsequent units can communicate and read by a third party).
● It supports real-time automatic clock timing.
● It has secondary development function (the ladder diagram programming or configured software can meet subsequent communication and logical modification).
● It has the function of receiving and transmitting GPRS data.
