Why Choose the TE Connectivity RIHE-1611-FSWC-24VDC Decoupling Interface?

The TE Connectivity RIHE-1611-FSWC-24VDC, part number 1SNA020800R0200, is a professional 16-channel relay decoupling interface designed for industrial control, PLC and automation systems. Part of the established Entrelec Interfast range, it provides an organised interface between electronic control equipment and field devices, allowing low-level control signals to operate external loads through electrically isolated relay contacts.

Designed around a 24 V DC relay control voltage, the RIHE-1611-FSWC-24VDC incorporates 16 relay channels with normally open (1NO) contacts. The interface also incorporates fuse and switching functionality, helping simplify protection, isolation, testing and maintenance of individual output circuits within industrial control panels.

The RIHE-1611-FSWC-24VDC is designed for DIN rail mounting and uses pluggable screw clamp connectivity for practical field wiring. With a rated current of 5 A, its integrated multi-channel architecture can significantly reduce panel wiring compared with assembling equivalent relay, fuse and switching functions from individual components.

Key Advantages

• Integrated 16-channel relay decoupling interface for industrial automation systems.

Reliable Relay Isolation for Industrial Automation

Relay decoupling interfaces provide an electrical separation layer between PLC or electronic controller outputs and field equipment. Instead of connecting a controller output directly to a load, the control signal energises a relay whose contact switches the external circuit. This arrangement helps isolate sensitive control electronics while providing a practical interface for industrial loads.

The TE Connectivity RIHE-1611-FSWC-24VDC combines 16 relay channels with fuse and switching functions in one Interfast assembly. This integrated approach reduces the number of separately installed components required in a control cabinet while making individual circuits easier to protect, isolate and service.

Typical Applications

• PLC digital output interfacing.
• Industrial control panels and electrical cabinets.
• Factory automation and production machinery.
• Relay isolation between controllers and field equipment.
• Process control and instrumentation systems.
• Machine control and material handling equipment.
• DIN rail mounted automation and interface assemblies.
