Connecting Sensors and Peripherals
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 Devices & Drivers for a place to start.
The two green screw terminals on the bottom of the ezeio has the following functionality:
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.

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).

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.

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.

CAN
The CAN port allows for interfacing with other CAN/J1939 devices. This is common in vehicles and engine control applications.

Modbus/TCP
The Ethernet port also supports third party devices, compatible with Modbus/TCP.

ezeio custom expansion
The ezeio also has an expansion port on the side for eze System's own expansion devices.
