1. Product Overview

• Model: BM‑xx00‑RM1K (BM‑0868‑RM1K / BM‑0900‑RM1K / BM‑0915‑RM1K / BM‑2400‑RM1K)

• Function: DIN‑rail, bidirectional wireless I/O radio kit (no programming required)

• Purpose: Replace hardwired I/O with secure, long‑range wireless; ideal for remote sites, retrofits, and cost‑sensitive installations where running cables is impractical.

  

2. Key Features

Wireless

• ISM bands:

  • 868 MHz (EU): up to 1 mile

  • 900 MHz (US): up to 4 miles

  • 2.4 GHz (US): up to 1 mile

• Factory‑paired & encrypted (AES): no configuration, secure out‑of‑the‑box

• Bidirectional: I/O replicated both ways between paired modules

I/O Capacity

• Digital: 16 channels (in/out, 24 VDC)

• Analog: 4–20 mA / 0–10 V (optional modules)

• Peer‑to‑peer: connect up to 16 I/O modules per radio pair

General

• No programming: wire‑and‑play (screwdriver only)

• DIN‑rail mount

• Industrial temp: ‑40°C to +75°C

• Certifications: CE, UL, RoHS, FCC
