1sna631219r0300 – bri-1221 n-1
TE Connectivity BRI-1221 N-1 1SNA631219R0300 is a 12-channel relay output decoupling interface with 1 SPDT 6 A relay contacts, a 16-pole Omniconnect interface and screw-clamp field connections for industrial automation systems.
Why Choose the TE Connectivity BRI-1221 N-1 1SNA631219R0300 Decoupling Interface?
The TE Connectivity BRI-1221 N-1 1SNA631219R0300 is a compact 12-channel relay output decoupling interface designed for reliable signal isolation and switching between industrial controllers and field equipment. Part of the established ENTRELEC interface system, it integrates multiple relay outputs into a single DIN-rail-mounted assembly to simplify control-panel wiring.
The BRI-1221 N-1 incorporates 12 relays with 1 SPDT contact per relay, providing changeover switching for industrial automation circuits. Each relay output is rated up to 6 A, making the module suitable for interfacing PLC and controller signals with field-side devices while providing relay-based electrical separation.
A 16-pole Omniconnect interface provides the multi-pole controller-side connection, while screw-clamp terminals accommodate individual field wiring. Measuring approximately 85 × 92 × 106 mm and weighing approximately 574 g, the module provides a space-efficient solution for control cabinets using standard 35 × 7.5 mm DIN rail.

Reliable Relay Isolation for Industrial Automation
Relay decoupling interfaces provide an effective transition between controller signals and field-side loads. By using individual electromechanical relay contacts, the interface provides electrical separation while allowing automation controllers to switch external devices without routing the field load directly through the controller output circuitry.
The BRI-1221 N-1 combines 12 relay channels with a multi-pole Omniconnect controller interface and individual screw-clamp field connections. This arrangement helps reduce wiring complexity, improve cabinet organisation and make commissioning, troubleshooting and maintenance more straightforward.
Typical Applications
- PLC output isolation and relay interfacing.
- Industrial automation control panels.
- Machine-building electrical systems.
- Process-control installations.
- Actuator, solenoid and contactor switching circuits.
- OEM machinery and automation cabinets.
