I/O modules sense on/off voltage levels to monitor power status
NT2140 discrete AC I/O module has been added to the BusWorks NT Ethernet I/O family, and provides six 120 V or 240 V AC optocoupler inputs for sensing the presence or absence of voltage, plus two DC logic I/O channels to monitor/control TTL or 0-32V logic levels. A network interface supports Modbus TCP/IP, EtherNet/IP or Profinet protocols to communicate with programmable controllers (PLC/PAC) or other networked devices. An OPC UA server, MQTT client, and RESTful API support Industrial Internet of Things (IIoT) applications.
NTE Ethernet models provide dual RJ45 ports for communication, plus discrete I/O channels. NTX expansion modules add extra I/O channels to monitor more devices. Up to three NTX modules can link to the NTE communication module through an integrated DIN rail bus, interfacing up to 64 I/O over one network IP address. Other NT Series analog and discrete I/O modules offering signal processing functions can also be combined to monitor or control voltage, current, and temperature signals.
