Bosch HCR-BU2 — Standalone 433MHz Receiver in Enclosure, Dual SPDT
A standalone 433 MHz receiver with two SPDT relay outputs, supplied in its own blue enclosure for DSRF-style wireless switching. It takes 12 or 24V AC or DC, so it drops onto existing gate, door or industrial control wiring without a supply change.
Key Details
- Supplied in an enclosure — Housed and ready to mount rather than a bare board needing a box found for it.
- Two SPDT relays — Two independent switched circuits from one receiver.
- 12 or 24V, AC or DC — Fits the supply already present on most gate and door control gear.
- DSRF-style switching — Suits wireless switching applications rather than alarm reporting.
- No panel needed — Operates entirely independently of any alarm system.
Where It Fits
Wireless switching where the installation point already has 12 or 24V available — gate controllers, door operators, industrial control panels. The RF159 covers a wider 9–28V input if the available supply is unusual.
