RX3i I/O is designed for critical missions, discrete and process applications. The rack-based I/O offers advanced diagnostics and excellent flexibility, with a wide range of standard and advanced I/O.
Input modules provide the interface between the PLC and external input devices such as proximity sensors, push buttons, switches and BCD thumbwheels. Output modules provide the interface between PLC and external output devices such as contactors, intermediate relays, BCD displays and indicator lights.
Emerson offers easy-to-use analog modules and HART analog modules for control processes such as flow, temperature and pressure.
The RX3i features a wide range of special modules to meet specific application requirements. These modules include:
The RX3i offers several communication options for distributed control and / or I/O. Choose from Ethernet EGD, Profibus-DP, Genius and DeviceNet. These communication modules are easy to install and quick to configure.
This output module provides 11 pneumatic outputs and five 24 VDC sourcing outputs. For each pneumatic output, the module contains an internal 3-way solenoid valve and an associated output fitting. Power source is supplied from a 24 VDC source to the "DC Outputs" jack on the front panel.
The RX3i supports various expansion options for local and remote I/O to optimize configurations. The RX3i can be expanded up to 8 expansion bases using the local external expansion module. The RX3i also supports remote Ethernet I/O using the RX3i Ethernet Network Interface Module (IC695NKT001) Series 90-30 Ethernet Network Interface Module (IC693NIU004) for more distributed I/O.
