IO MAX Transmitter

The Oleumtech IO MAX (MX1) is the most flexible, self-contained Multi-I/O Wireless Transmitter available.

The 4 analog inputs can be independently set for any combination of 4-20 mA or 0-10 VDC via DIP switches. When IO MAX is used with the optional Solar Power Pack option, each sensor can be powered by switchable 12 VDC or 12-18 VDC continuous power supply. External power can be supplied for continuous and higher power requirement. The 2 digital inputs can be set as normally open or normally closed and are rated up to 24 VDC. The 2 digital open-drain outputs can sink up to 1 Amp of current.

The IO MAX Transmitter can be configured as a Modbus Master and multi-drop up to 16 instruments. The IO MAX Transmitter works with an external 9-24 VDC power source or with the optional OleumTech SX1000-SP2, 5 Watt 12 VDC CID2 Solar Power Pack.  This flexible cost- effective solution is completely self-contained and ready-to- deploy!

The IO MAX Transmitter is configured using BreeZ® Software by OleumTech, provided free of charge. IO MAX is one of many Wireless Transmitters that communicates with an OleumTech Wireless Gateway within its network, creating a highly scalable network, accommodating virtually any I/O requirement.Oleumtech IO Max Transmitter Network Diagram
