Product Description
Product Overview
The Honeywell IOTA-R24 FC-RUSIO-3224 Redundant IO Termination Assembly (IOTA) is a critical component designed to support a redundant pair of RUSIO-3224 or RUSLS-3224 I/O modules within Honeywell’s industrial control systems, such as Safety Manager or Experion platforms. This assembly ensures reliable signal termination and power distribution for redundant I/O configurations, featuring robust environmental tolerances, multiple connection types, and certifications from CE, UL, and TUV. Physical and schematic details are referenced in Figures 1 and 2 of the original documentation.
General Description
- The IOTA-R24 assembly enables the use of a redundant set of RUSIO-3224 or RUSLS-3224 modules.
- For physical and schematic representations, see Figure 1 and Figure 2.
