Ethernet Analog IO Modules NT2220

The NT2220 modules offer 16 current inputs. Each input supports bipolar and unipolar ranges with 16-bit A/D. This type of model offers a compact network interface to monitor sensor levels or 4-20mA loops.

NTX Expansion models can interface up to 64 current inputs on a single IP address.

The Acromag NT2220 is an Ethernet Analog IO Module.

Firstly, the BusWorks® NT2000 Series offer a modular solution for Ethernet remote I/O Systems. Two module types are available. The first module is the NTE Ethernet model. It provides the protocol interface plus I/O signal processing channels. The second module is the NTX Expansion. It allows extra I/O channels when mated to any NTE Ethernet communication module.

Therefore, applications include collecting pressure, level, flow, temperature and other data from sensors, transducers or transmitters. The 4-20mA current loop is the most common process control signal in many industries. The NT2220 modules offer 16 current inputs and each input supports bipolar and unipolar ranges using a 16-bit A/D Card.

Secondly, an isolated RS-485 bus links up to three expansion modules to the Ethernet module. Connectors join it to the DIN rail. An internal NT bus distributes power and communication between the modules. Allowing users to mix analog, temperature and discrete I/O modules across the NT bus. Direct Peer to peer or multicast communication between remote modules without master controller is available through Acromag’s i2o messaging technology.
