This section includes distributed I/O modules that use Ethernet for connection to your computer or network. Sometimes referred to as I/O servers or I/O gateways, Distributed Ethernet I/O modules monitor temperature, volts or mA signals, and pass the measured values back to your master computer using Modbus/ TCP or other Ethernet based protocols.
Digital status signals such as alarms or switches can also be monitored, while digital outputs can control pumps or other on/off devices.
In addition to monitoring and control of signals over Ethernet, extra features are provided depending on which model is selected. These may include peer-to-peer communications, on-board logic control and Active messaging. Distributed Ethernet I/O is especially useful for transmitting digital signals from one location to another without the need for a controller or PC
