XT1120: 16-Channel Discrete Ethernet I/O Modules
with Sourcing Outputs
XT1121: Modbus/TCP and i2o protocol
XT1122: Ethernet/IP protocol
XT1123: Profinet protocol
The XT1120 interfaces discrete I/O signals between measurement and control devices over Ethernet. Channels are individually configurable for input or high-side switched output operation.
Rugged construction, high density design, and easy USB-to-PC/Windows setup combine for a very effective I/O solution. These units are ideal for remote monitoring, distributed control, or SCADA applications.
