When 1 channel isn’t enough
Most off-the-shelf RF relay receivers are single-channel — fine for one light or one lock, but useless for a roller shutter (up / stop / down / lock) or a 3-zone industrial lighting setup. The FRAWR01 ships with 4 independent 10 A relays in one compact ABS housing, with selectable momentary / toggle / latching modes per channel — the wholesale-priced alternative to stacking four single-channel hobby boards.
Why 4 channels, not 1 or 8
- 1 channel is too restrictive — most real applications need at least 2 (up/down) or 3 (up/stop/down).
- 8 channels is overkill for most industrial use cases and makes the wiring layout complex.
- 4 channels covers ~90 % of small-to-mid industrial wireless switching: roller shutters, 4-zone lighting, 2 garage doors + 2 gates, irrigation + lighting, etc.

The 3 modes — when to use each
Momentary
Relay closes while button is held; opens on release. Best for electric locks, momentary triggers, deadman switches. Common in industrial safety controls.
Toggle
Press once to close, press again to open. Best for general on/off lighting, pump control, anywhere you want a simple state switch.
Latching
One button latches the relay on; a different button latches it off. Best for sequencing — roller shutter up / stop / down, irrigation zones where zone 1 must close before zone 2 opens, etc.
Mode selection is via on-board DIP switches, per channel. A buyer can configure channel 1 as momentary, channel 2 as toggle, channel 3 as latching-up, channel 4 as latching-down — all on one FRAWR01.
Compatible brands & pairing
FRAWR01 pairs with any 433 MHz fixed-code remote (EV1527, PT2262, PT2240) and most rolling-code remotes (HCS301, KeeLoq). Confirmed-working with:
- Industrial control: warehouse lighting, parking lot floodlights, factory floor machinery isolation
- Agriculture: irrigation pump control via wireless remote — no trenching needed across fields
- Garage / gate: roller shutter with up / stop / down / lock; dual-gate installations
- Lighting: 4-zone smart-lighting with a single FRAWR01 + 4 standard RF remotes
Wholesale-distinct advantages vs the alternatives
- 4 channels in one housing — competitors ship single-channel boards. Stacking 4 single-channel boards means 4 × the wiring time, 4 × the failure points, 4 × the DIN-rail space.
- DC 6 – 24 V wide-voltage input — one SKU covers 12 V automotive, 24 V industrial, and 6 V low-power installations. No need to stock multiple voltage variants.
- 30 paired-remotes memory — sufficient for a multi-tenant apartment complex or a 30-employee factory floor.
- External SMA antenna included — most competitor boards ship with a stubby PCB antenna that loses 6–8 dB. The included SMA helical antenna gives reliable range in industrial environments.
- DIP-switch per-channel mode — no firmware reprogramming required to reconfigure modes. Field-installable.
- Factory-direct pricing — $6.80 MOQ 100, vs $9–12 from Alibaba trading companies for comparable boards.

FAQ
Q: Can FRAWR01 control a 3-phase industrial motor?
A: The relay contacts are rated 10 A / 250 VAC. For a 3-phase motor (typically 380–415 VAC), you need a contactor in between — FRAWR01 drives the contactor coil, the contactor switches the motor.
Q: What’s the maximum range?
A: With the included external SMA antenna, open-air range is ~100 m. Indoor / industrial environment with concrete walls, typical range is 30–50 m.
Q: Can one remote control multiple FRAWR01 receivers?
A: Yes. A single remote can pair with up to 30 receivers, and each FRAWR01 stores up to 30 remotes. Useful for one remote controlling 4 different installations across a property.
Q: Does FRAWR01 support 315 MHz (North America)?
A: Standard SKU is 433.92 MHz. 315 MHz variant is available at 500+ MOQ — contact for quote.
FRAWR01 is part of Gemu RF’s Smart Controllers & Receivers category, alongside the TY-R1 3-channel receiver and TW01 Wi-Fi adapter.
