1. Product Title

ABB 1SNA631125R1500 (BRI‑16N)‑ 16‑Channel Relay Interface Module

2. Product Overview

1SNA631125R1500, BRI‑16N, is ABB Entrelec OMNICONNECT series DIN‑rail mount multi‑channel relay interface terminal block. It integrates 16 pieces 1SPDT relay channels, converts controller logic signals into isolated relay contact outputs for field‑device switching. Each relay contact rated 6 A, 24 VDC coil power supply, plug‑in screw‑clamp terminal design simplifies field wiring and module replacement without cable re‑termination. Clear channel status indicator windows support fast on‑site fault diagnosis. Widely used as interface spare for PLC/DCS discrete‑output cabinet systems.
