BusWorks NT series remote I/O modules provide an Ethernet interface for analog, discrete and temperature signals. NTE Ethernet I/O models have dual RJ45 ports and a Web server with Modbus TCP/IP communication to monitor or control the internal I/O channels. An integrated DIN rail bus allows connection of up to three NTX expansion I/O modules. Each I/O module adds up to 16 input or output signals, allowing a mix of voltage, current, temperature, TTL and relay control signals networked on one IP address. The space-saving design requires only 25 mm of DIN rail per module. The operating temperature range is -40 to 70 °C.
