GEKKO - battery-powered data logger
Perfect for overflow registration
GEKKO - Battery-powered data logger with modem
GEKKO data logger is designed in a robust industrial design. It can be supplied using either the 2 pcs. lithium batteries or external voltage supply 12-30V DC.
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
GEKKO data logger can communicate via standard MODBUS TCP/IP or SMS commands. Communication takes place via 4G modem (2G, 3G and 4G) or Sigfox modem – both are mounted on their own print. Thus, communication can be changed to future form of communication without changing the entire data logger.
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.
