==== Connecting Sensors and Peripherals ==== {{indexmenu_n>600}} The ezeio can connect to a large variety of sensors and peripherals. eze System manufacture and sell some compatible sensors and devices, but many third-party devices also work with the ezeio thanks to the ezeio having a multitude of interfaces. Simply connecting a sensor or device is usually not enough to make it work. You will also need to configure the ezeio to use the sensor or device. See [[ezeio2:userinterface:configuration:devicelist]] for a place to start. The two green screw terminals on the bottom of the ezeio has the following functionality: {{:ezeio2:ezeio-green-terminal-overview.png|}} The terminals are removable to simplify wiring. === Discrete inputs === The 8 discrete inputs are individually configurable to measure voltage (0-10VDC), current (0-30mADC), resistance (0-500000 Ohm) or pulses. More details : [[ezeio2:connections:inputs|]] === Outputs === Output 1 and 2 are active on/off outputs, and outputs the supply voltage when active. Output 3 can be used as a PWM output, or as a on/off output like 1&2. Output 4 outputs a DC voltage 0-10V (max 20mA). More details : [[ezeio2:connections:outputs|]] === SDI-12 === The SDI-12 port conforms to the SDI-12 v1.3 standard, and allows for connection of various sensors and instruments. Sensors for environmental monitoring often support SDI-12. More details : [[ezeio2:connections:sdi12|]] === Modbus/RTU === The Modbus/RTU port is commonly used with third party devices, such as energy meters, temperature controllers, sensors, VFD's, I/O expansion and much more. Modbus/RTU is one of the most common interfaces in the industry. More details : [[ezeio2:connections:modbusrtu|]] === CAN === The CAN port allows for interfacing with other CAN/J1939 devices. This is common in vehicles and engine control applications. More details : [[ezeio2:connections:can|]] === Modbus/TCP === The Ethernet port also supports third party devices, compatible with Modbus/TCP. More details : [[ezeio2:connections:modbustcp|]] === ezeio custom expansion === The ezeio also has an expansion port on the side for eze System's own expansion devices.
