16-Channel Ethernet Discrete I/O Modules XT1120

The XT1120 Modules interfaces discrete I/O signals between measurement and control devices over Ethernet.

Channels are individually configurable for input or high side switched output operation.

The Acromag XT1120 provides 16-Channel Ethernet Discrete I/O Modules.

Firstly, there are 16 discrete tandem input/output channels in this model. They have Input and output ranges of 0-32V DC. The input has TTL thresholds and the output uses open-source up to 300mA. It uses Modbus TCP/IP, Ethernet/IP, Profinet or i2o as the Ethernet Communication. Plus, requires a power source of 12 to 32V DC (or 2.5W).

Secondly, this module has a rugged, high density design. As well as an easy USB-to-PC/Windows setup to make an effective I/O solution.

Ideal for remote monitoring, distributed control or SCADA applications.

To prevent damage or errors from grounded PCs and surges, Acromag strongly recommends use of the USB-ISOLATOR when configuring an XT1000 I/O module.

Features of the 16-Channel Ethernet Discrete I/O Modules XT1120 include:

  • i2o® peer-to-peer available for Modbus TCP/IP only
  • 16 solid-state discrete I/O channels (any mix of inputs or outputs)
  • Built-in 10K ohm pull-up resistors for 2/3-wire sensors (contacts, proximity, TTL)
  • Configurable normal/reverse input logic
  • Open-drain outputs switch up to 300mA each and include built-in read-back capability
  • Easy setup with Windows software via USB
  • Watchdog timer control of failsafe outputs
  • Continuously changing “heart-beat” register validates module operation
  • High-Density 22.5mm wide package with pluggable, front-facing terminals
  • Dual Ethernet 10/100 ports (auto-negotiation) reduce switch port requirements
  • 1500V AC isolation (between I/O, power, and network ports) and surge/transient protection
  • Supports bused/rail and redundant power
  • -40°C to 70°C wide temperature operation
  • Withstands 25g shock and 4g vibration
  • CE and UL/cUL Class 1 Div 2 Zone 2 approvals ATEX Certified.
