Product short description:
  • 6 mechanical relay outputs
  • 6 discrete inputs
  • Ethernet I/O plus Expansion I/O
  • Multi-protocol support

NT2130 modules offer six 5A mechanical relays and six discrete inputs. The NTE Ethernet I/O models provide a compact network interface to monitor and control discrete device levels. Appending NTX expansion models can interface up to 24 relays and 24 level sensing inputs on a single IP address.

NT2130 Ethernet Digital I/O Modules Description

The BusWorks® NT2131 Ethernet digital I/O modules with mechanical relays 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.

NT2130 modules offer six 5A mechanical relays and six discrete inputs. The NTE Ethernet I/O models provide a compact network interface to monitor and control discrete device levels.

Appending NTX expansion models can interface up to 24 relays and 24 level sensing inputs on a single IP address.

Applications include on/off monitoring and control of motors, pumps, lights, heaters, fans, etc. or the open/close status of valves, doors, and gates.

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.
