Product short description:
  • 16 single-ended voltage inputs
  • Ethernet I/O plus Expansion I/O
  • Multi-protocol support

NT2240 modules offer 16 voltage inputs. Each input supports bipolar and unipolar ranges with 16-bit A/D. NTE Ethernet models provide a compact network interface to monitor sensor levels or 0-10V devices. Appending NTX expansion models can interface up to 64 voltage inputs on a single IP address.

NT2240 Ethernet Analog I/O Modules Description

The BusWorks® NT2000 series offers a cost-effective, modular solution for Ethernet remote I/O systems. Two module types are available. NTE Ethernet models provide the protocol interface plus I/O signal processing channels. NTX expansion modules add extra I/O channels when mated to any NTE Ethernet communication module.

NT2240 modules offer 16 voltage inputs. Each input supports bipolar and unipolar ranges with 16-bit A/D. NTE Ethernet models provide a compact network interface to monitor sensor levels or 0-10V devices. Appending NTX expansion models can interface up to 64 voltage inputs on a single IP address.

Applications include collecting pressure, HVAC levels, temperature, and other data at sensors, transducers, or transmitters. The 0-10V signal is very commonly used for automation and environmental controllers.

An isolated RS-485 bus links up to three expansion modules to the Ethernet module with connectors that join along the DIN rail. This internal NT bus distributes power and communication between the modules. Users can mix analog, temperature, and discrete I/O modules across the NT bus.

Acromag’s i2o® messaging technology allows direct peer-to-peer or multicast communication between remote modules without a master controller.
