1sna020955r2000 – rihe-1611-n/p-in-24vdc

Why Choose the TE Connectivity RIHE-1611-N/P-IN-24VDC Interface Module?

The TE Connectivity RIHE-1611-N/P-IN-24VDC, manufacturer part number 1SNA020955R2000, is a 16-channel relay input decoupling interface from the ENTRELEC Interfast range. Designed for industrial automation and control-panel applications, it provides an organised interface between field signals and electronic control equipment while using relay contacts to provide electrical separation between connected circuits.

This specific IN version is designed as an input interface with 16 relays, each providing a 1NO normally-open contact rated at 5 A. Its nominal operating voltage is 24 V DC, making it well suited to common industrial control-voltage systems and PLC installations.

The RIHE-1611-N/P-IN-24VDC is designed for an HE10/20 interface connection, allowing multiple channels to be connected through a structured multi-pole interface rather than extensive individual point-to-point wiring. Its compact Interfast PCB measures approximately 50 × 47.5 mm, providing a high-density solution for industrial input interfacing and relay decoupling.

Reliable Relay Input Decoupling for Industrial Automation

Relay input interfaces provide a practical method of electrically separating field-side signals from PLCs and other electronic control equipment. This decoupling architecture is particularly useful where multiple industrial signals must be brought into a control system in an organised and serviceable manner.

The TE Connectivity RIHE-1611-N/P-IN-24VDC combines 16 relay channels, 1NO 5 A contacts and an HE10/20 interface within a compact Interfast PCB. The result is a high-density input interface suited to machine builders, panel manufacturers and automation engineers seeking to simplify multi-channel control-system wiring.

Typical Applications

• PLC input interfacing and relay decoupling.
• Industrial automation control cabinets.
• Machine building and production equipment.
• Process control and monitoring systems.
• Field-signal interfacing to electronic controllers.
• High-density 16-channel industrial input systems.
