1sna020832r1500 – ri-1622n/p-24vdc

Why Choose the TE Connectivity Entrelec RI-1622N/P-24VDC Relay Interface?

The TE Connectivity Entrelec RI-1622N/P-24VDC, manufacturer part number 1SNA020832R1500, is a 16-relay decoupling output interface from the Entrelec Interfast range. Designed for industrial automation and control-panel applications, it provides an efficient interface between PLC or controller outputs and field devices while consolidating multiple relay channels onto a compact printed circuit board assembly.

The RI-1622N/P-24VDC operates with a 24 V DC nominal control voltage and incorporates 16 relays, each with 2 changeover contacts (2CO / DPDT). The relay contacts are rated for up to 8 A, providing versatile switching capability for compatible industrial loads and control circuits.

Designed for connection through Omniconnect 20-pole and HE10/20 interfaces, the module simplifies multi-channel wiring between automation equipment and field circuits. With dimensions of approximately 104 × 70.5 mm, it provides 16 relay channels in a compact format that helps reduce point-to-point wiring and improve control-panel organisation.

Multi-Channel Relay Isolation for Industrial Automation

Relay interface modules provide an electrical switching layer between electronic controllers and field equipment. They allow low-power PLC or control signals to operate external circuits through relay contacts while providing galvanic separation between the control and switched sides of the application.

The TE Connectivity Entrelec RI-1622N/P-24VDC combines 16 relays with two changeover contacts per channel on a compact Interfast PCB. By using multipole Omniconnect and HE10 connectivity, the interface can substantially reduce conventional point-to-point wiring and provide a structured connection between automation controllers and field circuits.

Typical Applications

• PLC output interfacing.
• Industrial automation control panels.
• Machine control and OEM equipment.
• Relay isolation and decoupling circuits.
• Multi-channel field device switching.
• Process control and manufacturing automation systems.
• Control cabinets using Omniconnect or HE10 interfaces.
