Ethernet Remote I/O Modules for Ethernet – Busworks NT Series

Expandable Remote I/O

Acromag’s Busworks® NT Series lets you add expansion I/O modules for a high-density, cost-efficient remote I/O solution

Base unit NTE Ethernet models handle the network communication and interface up to 16 analog or digital I/O channels for remote monitoring or control applications. NTX Expansion models provide a cost-effective way to add a mix of I/O signal types under a single IP address.

Multi-protocol support

The NTE Ethernet I/O modules are pre-programmed to support Modbus/TCP, Ethernet/IP and Profinet protocols. Just select which is to be used. Modules also support direct i2o® peer-to-peer communication without a master.

• Integrated I/O expansion bus
• Up to 64 I/O channels per port
• Mix analog, digital, and temperature I/O on one port
• i2o peer-to-peer or multicast communications
• Rugged design, -40 to 70°C
• Hazardous location approvals

Ethernet expandable I/O modules can now process IF/THEN/ELSE logic for rule-based I/O operation.

Acromag’s new BusWorks^® NT series remote I/O modules are now enhanced with conditional logic. The conditional logic increases the functionality with a system of rules that allows extremely complicated decisions based on relatively simple “yes/no” questions. For example, reading an analog or digital input value can trigger an action to happen as a result. This value could be used to control a relay when one or more conditions occur. Another example would be when a discrete input is ON and a temperature threshold is crossed. More complex math computation and logic are also an option.

Conditional logic is configured on the NT’s built-in web configuration page. No programming is required. The modules support up to 64 conditions using IF/THEN/ELSE statements.

Ethernet-based Configuration

Easy setup from anywhere with a web browser

NTE Ethernet I/O modules have a built-in web server for convenient configuration without installing any software. Several web pages lead you through the options to set your IP addresses, protocol, and I/O parameters. A diagnostics page lets you monitor I/O values from your PC, tablet, or smartphone.

Advanced features for IIoT and local control logic functions

The configuration pages will help you quickly setup advanced capabilities such as peer-to-peer communication, conditional logic computation, and alarm output.

• Peer-to-peer communication
• Counter/timers
• IF/THEN/ELSE logic
• Alarm output*
• RESTful APIs*
