NT2320 Ethernet Analog Output Modules from Acromag

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.

NT2320 modules offer 8 voltage outputs. Each output is driven by a 16-bit DAC. NTE Ethernet models provide a compact network interface to control voltage signal levels. Appending NTX expansion models can interface up to 32 voltage outputs at a single IP address.

Applications include controlling analog actuator levels and driving recorders, displays, or other process instruments. Voltage outputs can control generator power, drive speed, or valve positioning.

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.
