16 discrete tandem input/output channels ◆ Modbus TCP/IP, Ethernet/IP or Profinet communication

Description
The XT1120 interfaces discrete I/O signals
between measurement and control devices overEthernet. Channels are individually configurable
for input or high-side switched output operation.
Rugged construction, high density design, andeasy USB-to-PC/Windows setup combine for avery effective I/O solution. These units are ideal
for remote monitoring, distributed control, orSCADA applications.

Input/Output Ranges
Input: 0-32V DC, TTL thresholds
Output: 0-32V DC, open-source, up to 300mA
Ethernet Communication
Modbus TCP/IP, Ethernet/IP, Profinet,i2o® peer-to-peer, 10/100Base-T(X)PriorityChannel™ device determinism
Power Requirement
12 to 32V DC (2.5W)
