Acromag - Ethernet I/O Modules 16-bidirectional discrete NT2120 Get latest price

The Acromag NT2120 provides 16-bidirectional discrete Ethernet I/O Modules.

Firstly, the modules are part of the Acromag BusWorks NT2000 Series family. This is a cost effective and modular solution for Ethernet Remote I/O Systems.

There are two components to this series. The NTE Ethernet Models (which the NT2120 is) provide the protocol interface and the I/O signal processing channels. The NTX Expansion modules add extra I/O channels when paired to any NTE Ethernet Communication module. Therefore, the NT2120 modules offer 16 bi-directional discrete I/O channels for monitoring or controlling discrete device levels. Then the appending NTX expansion model can be added to interface up to 64 discrete I/O channels on single IP address.

Applications include monitoring and control of relays, contact closures, solenoids, TTL logic and discrete sensors on motors, lamps, valves and doors.

Finally an isolated RS-485 links up to three expansion modules to the Ethernet module with connectors that join the DIN rail. This internal NT bus distributes power and communication between the modules. Allow users to mix analog, temperature and discrete I/O modules across the NT bus. Acromag’s i2o messaging technology enables direct peer to peer or multicast communication between remote modules without a master controller.

Features of the 16-bidirectional discrete Ethernet I/O Modules NT2120 include:
