SONGLE SMI-12VDC-SL-2C Power Relay 2-Ch 12VDC Coil 5A 250VAC/30VDC 8 Pin

Description

SONGLE SMI-12VDC-SL-2C Power Relay 2-Ch 12VDC Coil 5A 250VAC/30VDC 8 Pin The SONGLE SMI-12VDC-SL-2C is a compact, sealed two-pole changeover (2-C) power relay in an 8-pin PCB package. Designed for PCB solder mounting, it packages two SPDT contact sets in one small footprint so designers can switch two independent circuits or provide double-pole switching for higher safety and isolation. The relay is intended for general power-control use where a small form factor, reliable contact switching and moderate load capacity are required. This relay uses metal alloy contacts (options include AgCdO, AgSnO₂, AgNi) and a coil driven at 12 VDC for the SMI-12VDC variant. It is a sealed construction (S = sealed, F = dust-proof versions exist) with a spring-type contact mechanism that yields consistent make/break behaviour. Typical operate and release times are short (≤ 10 ms), enabling responsive switching in control circuits. The SMI series is specified for wide environmental range (–40 °C to +85 °C) and rated for vibration and shock typical of industrial use. Insulation and dielectric values are high meeting reinforced insulation spacing and strong coil-to-contact dielectric withstand ratings so it is suitable where safety isolation and reliable long-term switching are needed. The relay’s small mass (~15 g) and PCB footprint make it a convenient choice for compact power/control modules. Features: Dual changeover contact configuration (2-C / two SPDT contacts). 5 A power contact rating for general AC/DC loads. Sealed (S) and dust-proof (F) package options for protection.
