FLEX I/O is a small, modular I/O system for distributed applications that performs all functions of rack-based I/O. The FLEX system contains the following components shown:
• Adapter – Transfers read and write configuration data to and from the I/O module.
• Terminal base – Contains a terminal strip to terminate wiring for two- or three-wire devices.
• I/O module – Contains the bus interface and circuitry that is needed to perform specific functions that are related to your application.
Types of Modules
The module refers to the following catalogs:
Catalog Number | Voltage | Inputs | Description |
1794-IRT8 | 24V DC | 8 | Analog – 8 pt, 16 bit non-isolated RTD, thermocouple, and mV Input module |
1794-IRT8XT | 24V DC | 8 | Analog – 8 pt, 16 bit non-isolated RTD, thermocouple, and mV Input module designed for extended temperature. |
The module accepts up to eight thermocouple or RTD inputs. The inputs are nonisolated and are selected with analog multiplexers. The inputs accept millivolt or resistive inputs. Default input spans are -40.00 mV… +100.00 mV or 0.0…500.0 Ω. Fault indicators are located field side.
No switches or jumpers are used on the TC and RTD Input module. The inputs have both fixed hardware filters and selectable firmware digital filters.
