NT2610 Ethernet Temperature Input Modules Description

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 eight I/O signal processing channels. NTX expansion modules add eight more I/O channels when mated to any NTE Ethernet communication module.

NT2610 modules offer 8 thermocouple/millivolt inputs and 2 bidirectional discrete digital I/O channels. Each input can support a variety of sensor types. NTE Ethernet models provide a network interface to monitor temperature levels. Appending NTX expansion models can interface up to 32 TC/mV sensor inputs at a single IP address.
Applications include monitoring temperatures in tanks, pipes, motors, heaters, chillers, and many industrial processes. Many pressure, weight, flow, and chemical sensors also provide a millivolt output.

An isolated RS-485 bus links up to three expansion modules to the Ethernet module with bus connectors that join units 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.
