RF Mando’s relay module family covers the full low-voltage control spectrum from 5 V logic-level triggering up to 72 V DC industrial switching. Panel builders, gate-opener OEMs, and access-control integrators in EU and CIS markets rely on our stock for rapid prototyping and field service.
Product Range
| Channels | Voltage | Isolation | Typical Use |
|---|---|---|---|
| 1 / 2 / 4 | 5 V / 12 V | Optocoupler 5 kV | Arduino, ESP32, MCU-driven relays |
| 1 / 2 | 24 V / 36 V | Optocoupler 5 kV | Gate controllers, shutter drives |
| 1 / 2 / 4 | 48 V / 72 V | Optocoupler + TVS | Industrial panel, solar charge control |
Why Integrators Choose RF Mando Relays
- Optocoupler isolation — protects MCU from inductive kickback and ground loops
- Low-level trigger — direct 3.3 V GPIO compatible, no transistor driver needed
- Pluggable screw terminals — field-serviceable without de-soldering
- LED per channel — one-glance diagnostics during commissioning
Wiring Reference (12 V / 4-channel example)
- Connect VCC to 12 V supply, GND to panel ground.
- Drive each IN1…IN4 pin from MCU GPIO (low-level trigger).
- Wire load between COM and NO (or NC) screw terminal.
- For DC inductive loads, add a flyback diode across the load.
