1sna020954r2700 – rihe-1611-n/p-24vdc interface module

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

The TE Connectivity RIHE-1611-N/P-24VDC, manufacturer part number 1SNA020954R2700, is a 16-channel relay output decoupling interface from the ENTRELEC Interfast range. Designed for industrial automation and PLC interfacing, it provides an organised method of converting electronic controller signals into isolated relay outputs for connection to field equipment.

This interface operates at 24 V DC and incorporates 16 normally-open relay outputs. Each relay provides a 1NO contact rated at 5 A, making the module suitable for switching a variety of industrial control circuits while electrically separating the controller side from the connected output circuits.

The RIHE-1611-N/P-24VDC is designed for connection through an HE10/20 interface, helping reduce conventional point-to-point wiring between PLC equipment and relay outputs. Its compact Interfast PCB format has a width of 50 mm and depth of 47.5 mm, providing a high-density 16-channel interface for space-conscious industrial control cabinets.

Reliable 16-Channel Relay Decoupling for Automation Systems

Relay output interfaces provide an effective method of separating sensitive PLC electronics from switched field circuits. The controller operates the relay coil while the relay contact switches the connected output circuit, providing galvanic separation and allowing the control system to interface efficiently with external industrial equipment.

The TE Connectivity RIHE-1611-N/P-24VDC combines 16 normally-open 5 A relay outputs with an HE10/20 connection in a compact Interfast PCB. This high-density architecture is particularly useful for machine builders and automation engineers who need to minimise wiring and panel space while maintaining accessible, organised relay outputs.

Typical Applications

• PLC output interfacing and relay isolation.
• Industrial automation control cabinets.
• Machine building and production equipment.
• Process control and instrumentation systems.
• Field-device and actuator control circuits.
• High-density 16-channel relay output installations.
