Made in Mainland China.

Key Features

• Dual Independent Channels: Signal 1 controls Relay 1; Signal 2 controls Relay 2 — they operate simultaneously yet completely independently.
• Wide Input Voltage Range: DC 7V–30V, making it compatible with most hobby and industrial power supplies.
• 32 Programmable Functions (P-11 to P-48): Covers jog, self-lock, pulse trigger, cycle timer, countdown, power-on delay, and much more.
• Adjustable Time Range: From 0.01 seconds to 999 minutes — any duration, fully customizable.
• 5A Load Capacity: Safely controls both DC and AC loads up to 5A, including motors, pumps, valves, and lighting.
• Non-Volatile Memory: All parameters for functions P-11 through P-44 are retained after power-off, so your settings are never lost.
• Comprehensive Manual Included: Clear wiring descriptions and full function list so you can get started right away.
