GEKKO
Battery-powered data logger with modem
GEKKO is equipped with 2 pcs. analog inputs which are 0/4-20mA or with 4 digital inputs, 2 of which can be configured as 0-10V inputs or as pulse inputs for counter. In addition, RS485 MODBUS communication with external devices is possible.
GEKKO is designed for use in wastewater and water supply applications and can collect data and log signals of several different types with the help of external equipment, e.g. used for H2S detection, level measurement, overflow registrations and for registration of precipitation events.
Communication to SCADA / SRO takes place through the program AcowaCore, which i.a. enables handling of an event-based logging function typically used in overflow registration.
GEKKO has a USB interface for programming GEKKO or for downloading logs in data loggers.
