Acromag - Model NT2120 - Ethernet Digital I/O Modules with Discrete Active High Input

NT2121 Ethernet digital I/O modules with discrete active high input an sourcing output 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. NT2120 modules offer 16 bidirectional discrete I/O channels for high-side (sourcing switch) applications. NTE Ethernet models provide a compact network interface to monitor or control discrete device levels. Appending NTX expansion models can interface up to 64 discrete I/O channels on a single IP address. 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.
