ZJ41S Interface Relay

Product Information

The ZJ41S is an ultra-thin (5 mm wide) solid-state relay (SSR) — 28 × 5 × 15 mm, single-row in-line PCB mounting. Fully electronic and maintenance-free: no mechanical action, no noise, no contact wear, with a built-in RC snubber and high EMC for harsh environments. AC-output types use a TRIAC; DC-output types use a power transistor (low-RDS 6 A option). Zero-crossing switching (random type optional).

Key features

  • Solid-state (SSR) — maintenance-free, long life; no mechanical action, noise, arcing or contact wear
  • Ultra-thin 5 mm — 28 × 5 × 15 mm; single-row in-line PCB mount, space-saving
  • Three output families — 2A (AC, TRIAC, 2 A) · 2D (DC, transistor, 2 A) · 6D (low-RDS DC, 6 A)
  • Zero-crossing turn-on / current-zero turn-off (random type optional)
  • Built-in RC surge-absorption snubber; high EMC for harsh environments
  • Wide DC input 5–60 V (05 / 12 / 24 / 32 / 60); input impedance 0.5–2.2 kΩ
  • 2500 V AC input-to-output isolation; ≥1000 MΩ; −30…+80 °C; ~20 g
